i2c: mvtwsi: fix reading status register after interrupt
The twsi_wait function reads the control register for interrupt flag,
and if interrupt flag is present, it immediately reads status register.
On our device this sometimes causes bad value being read from status
register, as if the value was not yet updated.
My theory is that the controller does approximately this:
1. sets interrupt flag in control register,
2. sets the value of status register,
3. causes an interrupt
In U-Boot we do not use interrupts, so I think that it is possible that
sometimes the status register in the twsi_wait function is read between
points 1 and 2.
The bug does not appear if I add a small delay before reading status
register.
Wait 100ns (which in U-Boot currently means 1 us, because ndelay(i)
function calls udelay(DIV_ROUND_UP(i, 1000))) before reading the status
register.

arm: mvebu: turris_omnia: add RESET button handling
There is a Factory RESET button on the back side of the Turris Omnia
router. When user presses this button before powering the device up and
keeps it pressed, the microcontroller prevents the main CPU from booting
and counts how long the RESET button is being pressed (and indicates
this by lighting up front LEDs).
The idea behind this is that the user can boot the device into several
Factory RESET modes.
This patch adds support for U-Boot to read into which Factory RESET mode
the user booted the device. The value is an integer stored into the
omnia_reset environment variable. It is 0 if the button was not pressed
at all during power up, otherwise it is the number identifying the
Factory RESET mode.
This patch also changes bootcmd to a special hardcoded value if Factory
RESET button was pressed during device powerup. This special bootcmd
value sets the colors of all the LEDs on the front panel to green and
then tries to load the rescue image from the SPI flash memory and boot
it.

...
uuid_gpt_misc=
6d6c9a36-e919-264d-a9ee-
bd00379686c7
While the uuids do change on every 'gpt write' command, the values
appear to be taken from the same pool, in the same order.
Assuming U-Boot with RANDOM_UUID=y is deployed on a large number of
devices, all those devices would essentially expose the same UUID,
breaking the assumption of system/RFS/application designers who rely
on UUID as being globally unique (e.g. a database using UUID as key
would alias/mix up entries/records due to duplicated UUID).
The root cause seems to be simply _not_ seeding PRNG before generating
a random value. It turns out this belongs to an established class of
PRNG-specific problems, commonly known as "unseeded randomness", for
which I am able to find below bugs/CVE/CWE:
- https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2015-0285
("CVE-2015-0285 openssl: handshake with unseeded PRNG")
- https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2015-9019
("CVE-2015-9019 libxslt: math.random() in xslt uses unseeded
randomness")
- https://cwe.mitre.org/data/definitions/336.html
("CWE-336: Same Seed in Pseudo-Random Number Generator (PRNG)")
The first revision [1] of this patch updated the seed based on the
output of get_timer(), similar to [4].
There are two problems with this approach:
- get_timer() has a poor _ms_ resolution
- when gen_rand_uuid() is called in a loop, get_timer() returns the
same result, leading to the same seed being passed to srand(),
leading to the same uuid being generated for several partitions
with different names
The above drawbacks have been addressed in the second version [2].
In its third revision (current), the patch reworded the description
and summary line to emphasize it is a *fix* rather than an improvement.
Testing [3] consisted of running 'gpt write mmc 1 $partitions' in a
loop on R-Car3 for several minutes, collecting 8844 randomly generated
UUIDS. Two consecutive cold boots are concatenated in the log.

This is caused by calling is_gpt_valid() twice (hence allocating pte
also twice via alloc_read_gpt_entries()) while freeing pte only _once_
in the caller of gpt_verify_headers(). Fix that by freeing the pte
allocated and populated for primary GPT _before_ allocating and
populating the pte for backup GPT. The latter will be freed by the
caller of gpt_verify_headers().

rockchip: spi: make optimised receive-handler unaligned-safe
To support unaligned output buffers (i.e. 'in' in the terminology of
the SPI framework), this change splits each 16bit FIFO element after
reading and writes them to memory in two 8bit transactions. With this
change, we can now always use the optimised mode for receive-only
transcations independent on the alignment of the target buffer.
Given that we'll run with caches on, the impact should be negligible:
as expected, this has no adverse impact on throughput if running with
a 960MHz LPLL configuration.

rockchip: spi: add driver-data and a 'rxonly_manages_fifo' flag
The SPI controller's documentation (I only had access to the RK3399,
RK3368 and PX30 TRMs) specifies that, when operating in master-mode,
the controller will stop the SCLK to avoid RXFIFO overruns and TXFIFO
underruns. Looks like my worries that we'd need to support DMA-330
(aka PL330) to make any further progress were unfounded.
This adds a driver-data structure to capture hardware-specific
settings of individual controller instances (after all, we don't know
if all versions are well-behaved) and adds a 'master_manages_fifo'
flag to it. The first use of said flag is in the optimised
receive-only transfer-handler, which can now request 64Kframe
(i.e. 128KByte) bursts of data on each reprogramming of CTRLR1
(i.e. every time through the loop).
This improves throughput to 46.85MBit/s (a 94.65% bus-utilisation).

rockchip: spi: add optimised receive-only implementation
For the RK3399-Q7 we recommend storing SPL and u-boot.itb in the
on-module 32MBit (and sometimes even larger, if requested as part of a
configure-to-order configuration) SPI-NOR flash that is clocked for a
bitrate of 49.5MBit/s and connected in a single-IO configuration (the
RK3399 only supports single-IO for SPI).
Unfortunately, the existing SPI driver is excruciatingly slow at
reading out large chunks of data (in fact it is just as slow for small
chunks of data, but the overheads of the driver-framework make it less
noticeable): before this change, the throughput on a 4MB read from
SPI-NOR is 8.47MBit/s which equates a 17.11% bus-utilisation.
To improve on this, this commit adds an optimised receive-only
transfer (i.e.: out == NULL) handler that hooks into the main transfer
function and processes data in 16bit frames (utilising the full with
of each FIFO element). As of now, the receive-only handler requires
the in-buffer to be 16bit aligned. Any lingering data (i.e. either if
the in-buffer was not 16-bit aligned or if an odd number of bytes are
to be received) will be handled by the original 8bit reader/wirter.
Given that the SPI controller's documentation does not guarantuee any
interlocking between the RXFIFO and the master SCLK, the transfer loop
will be restarted for each chunk of 32 frames (i.e. 64 bytes).
With this new receive-only transfer handler, the throughput for a 4MB
read increases to 36.28MBit/s (i.e. 73.29% bus-utilisation): this is a
4x improvement over the baseline.

rockchip: spi: only wait for completion, if transmitting
The logic in the main transmit loop took a bit of reading the TRM to
fully understand (due to silent assumptions based in internal logic):
the "wait until idle" at the end of each iteration through the loop is
required for the transmit-path as each clearing of the ENA register
(to update run-length in the CTRLR1 register) will implicitly flush
the FIFOs... transmisson can therefore not overlap loop iterations.
This change adds a comment to clarify the reason/need for waiting
until the controller becomes idle and wraps the entire check into an
'if (out)' to make it clear that this is required for transfers with a
transmit-component only (for transfers having a receive-component,
completion of the transmit-side is trivially ensured by having
received the correct number of bytes).
The change does not increase execution time measurably in any of my
tests.

rockchip: spi: fix off-by-one in chunk size computation
The maximum transfer length (in a single transaction) for the Rockchip
SPI controller is 64Kframes (i.e. 0x10000 frames) of 8bit or 16bit
frames and is encoded as (num_frames - 1) in CTRLR1. The existing
code subtracted the "minus 1" twice for a maximum transfer length of
0xffff (64K - 1) frames.
While this is not strictly an error (the existing code is correct, but
leads to a bit of head-scrating), fix this off-by-one situation.

In analysing delays introduced for large SPI reads, the absence of any

Add an additional debug-only debug message to record the insertion and

ARM: socfpga: Remove socfpga_sdram_apply_static_cfg()
The usage of socfpga_sdram_apply_static_cfg() seems rather dubious and
is confirmed to lead to a rare system hang when enabling bridges. This
patch removes the socfpga_sdram_apply_static_cfg() altogether, because
it's use seems unjustified and problematic.
The socfpga_sdram_apply_static_cfg() triggers write to SDRAM staticcfg
register to set the applycfg bit, which according to old vendor U-Boot
sources can only be written when there is no traffic between the SDRAM
controller and the rest of the system. Empirical measurements confirm
this, setting the applycfg bit when there is traffic between the SDRAM
controller and CPU leads to the SDRAM controller accesses being blocked
shortly after.
Altera originally solved this by moving the entire code which sets the
staticcfg register to OCRAM [1]. The commit message claims that the
applycfg bit needs to be set after write to fpgaportrst register. This
is however inverted by Altera shortly after in [2], where the order
becomes the exact opposite of what commit message [1] claims to be the
required order. The explanation points to a possible problem in AMP
use-case, where the FPGA might be sending transactions through the F2S
bridge.
However, the AMP is only the tip of the iceberg here. Any of the other
L2, L3 or L4 masters can trigger transactions to the SDRAM. It becomes
rather non-trivial to guarantee there are no transactions to the SDRAM
controller.
The SoCFPGA SDRAM driver always writes the applycfg bit in SPL. Thus,
writing the applycfg again in bridge enable code seems redundant and
can presumably be dropped.

The driver currently calculates the end address of cache flush operation
for the DMA descriptors by adding cacheline size to the start address of

in some unlikely cases, smaller than the DMA descriptor size. Replace the
addition with roundup() applied on the end address of the last DMA
descriptor to round it up to the nearest cacheline size multiple.
