mx6: drop ARM errata 742230

Commit e9fd66defd7e (ARM: mx6: define CONFIG_ARM_ERRATA_742230) enables
errata 742230 for imx6, because it helps remove one reboot issue.
However, this errata does not really apply on imx6, because Cortex-A9
on imx6 is r2p10 while the errata only applies to revisions r1p0..r2p2.

At a later time, commit f71cbfe3ca5d (ARM: Add workaround for Cortex-A9
errata 794072) adds support of errata 794072, which applies to all
Cortex-A9 revisions.  As the workaround for both errata are exactly
same, it makes a lot more sense to select 794072 instead of 742230 for
imx6.  Since we already enable 794072 for imx6, it's time to drop
errata 742230 to avoid confusion.

spl: consolidate arch/arm/include/asm/arch-*/spl.h

arch/arm/include/asm/spl.h requires all SoCs to have
arch/arm/include/asm/arch-*/spl.h.

But many of them just define BOOT_DEVICE_* macros.

Those macros are used in the "switch (boot_device) { ... }"
statement in common/spl/spl.c.

So they should not be archtecture specific, but be described as
a simpile enumeration.

This commit merges most of arch/arm/include/asm/arch-*/spl.h
into arch/arm/include/asm/spl.h.

With a little more effort, arch-zynq/spl.h and arch-socfpga/spl.h
will be merged, while I am not sure about OMAP and Exynos.

serial_mxc: disable new features of autobaud detection

Bit 7 of UCR3 is described in the i.MX3x/i.MX5x/i.MX6x
reference manuals as follows:

Autobaud Detection Not Improved-. Disables new features of

1 Keep old autobaud detection mechanism

On at least i.MX6DQ, i.MX6DLS and i.MX53, the "new features"
occasionally cause the receiver to get out of sync and
continuously produce received characters of '\xff'.

This patch disables the "new feature" on all boards, since
there's no support for auto-baud in U-Boot on any of them.

Subject: [PATCH] net/designware: reorder struct dw_eth_dev to pack more
 efficiently.

The {tx,rx}_mac_descrtable fields are aligned to ARCH_DMA_MINALIGN, which could
be 256 or even larger. That means there is a potentially huge hole in the
struct before those fields, so move them to the front where they are better
packed.

Moving them to the front also helps ensure that so long as dw_eth_dev is
properly aligned (which it is since "net/designware: ensure device private data
is DMA aligned.") the {tx,rx}_mac_descrtable will be too, or at least avoids
having to worry too much about compiler specifics.

The {r,t}xbuffs fields also need to be aligned. Previously this was done
implicitly because they immediately followed the descriptor tables. Make this
explicit and also move to the head of the struct.

It's "correct" in so far as it works (the boards.cfg config stuff

...I had thought that it was to support some other board which wasn't
being upstreamed right now, so eventually useful and harmless for now,
but I've just checked and it isn't actually used by any of the boards in
u-boot-sunxi.git. So rather than fix it to use #ifdef lets drop it.

ARM: omap: merge GPMC initialization code for all platform

GPMC controller on TI's OMAP SoC is general purpose controller to interface
with different types of external devices like;
 - parallel NOR flash
 - parallel NAND flash
 - OneNand flash
 - SDR RAM
 - Ethernet Devices like LAN9220

Though GPMC configurations may be different for each platform depending on
clock-frequency and external device interfacing with controller. But
initialization sequence remains common across all platfoms.

Thus this patch merges gpmc_init() scattered in different arch-xx/mem.c
files into single omap-common/mem-common.c

However, actual platforms specific register config values are still sourced
from corresponding platform specific headers like;
 AM33xx: arch/arm/include/asm/arch-am33xx/mem.h
 OMAP3:  arch/arm/include/asm/arch-omap3/mem.h
 OMAP4:  arch/arm/include/asm/arch-omap4/mem.h
 OMAP4:  arch/arm/include/asm/arch-omap5/mem.h

Also, CONFIG_xx passed by board-profile decide config for which set of macros
need to be used for initialization

omap: overo: allow the use of a plain text env file instead boot scripts

Adapted from d70f5480 described below.

    commit d70f54808dfa83b574e1239c3eccbcf3317343e1
    Author: Javier Martinez Canillas <javier@dowhile0.org>
    Date:   Mon Jan 7 03:51:20 2013 +0000

    omap4: allow the use of a plain text env file instead boot scripts

    For production systems it is better to use script images since
    they are protected by checksums and carry valuable information like
    name and timestamp. Also, you can't validate the content passed to
    env import.

    But for development, it is easier to use the env import command and
    plain text files instead of script-images.

    Since both OMAP4 supported boards (Panda and TI SDP4430) are used
    primarily for development, this patch allows U-Boot to load env var
    from a text file in case that an boot.scr script-image is not present.

    The variable uenvcmd (if existent) will be executed (using run) after
    uEnv.txt was loaded. If uenvcmd doesn't exist the default boot sequence
    will be started.

disk: support devices with HW partitions

Some device types (e.g. eMMC) have hardware-level partitions (for eMMC,
separate boot and user data partitions). This change allows the user to
specify the HW partition they wish to access when passing a device ID to
U-Boot Commands such as part, ls, load, ums, etc.

The syntax allows an optional ".$hwpartid" to be appended to the device
name string for those commands.

Existing syntax, for MMC device 0, default HW partition ID, SW partition
ID 1:

ls mmc 0:1 /

New syntax, for MMC device 0, HW partition ID 1 (boot0), SW partition
ID 2:

ls mmc 0.1:2 /

For my purposes, this is most useful for the ums (USB mass storage
gadget) command, but there's no reason not to allow the new syntax
globally.

This patch adds the core support infra-structure. The next patch will

esdhc/usdhc: Fix PIO mode bug in fsl_esdhc driver

When configure the fsl_esdhc driver to PIO mode by defining
"CONFIG_SYS_FSL_ESDHC_USE_PIO", the SD/MMC read and write will fail.

Two bugs in the driver to cause the issue:
1. The read buffer was invalidated after reading from DATAPORT register,
which should be only applied to DMA mode. The valid data in cache was
overwritten by physical memory.
2. The watermarks are not set in PIO mode, will cause according state not
be set.
