Alexey Brodkin [Mon, 29 Dec 2014 12:42:57 +0000 (15:42 +0300)]
arc: introduce "mdbtrick" target

MetaWare debugger (MDB) is still used as a primary tool for interaction
with target via JTAG. Moreover some very advanced features are not yet
implemented in GDB for ARC (and not sure if they will be implemnted
sometime soon given complexity and rare need for those features for
common user).

So if we're talking about development process when U-Boot is loaded in
target memory not by low-level boot-loader but manually through JTAG
chances are high developer uses MDB for it.

But MDB doesn't support PIE (position-independent executable) - it will
refuse to even start - that means no chance to load elf contents on
target.
Then the only way to load U-Boot in MDB is to fake it by:
  1. Reset PIE flag in ELF header
     This is simpe - on attempt to open elf MDB checks header and if it
doesn't match its expectation refuces to use provided elf.
  2. Strip all debug information from elf
     If (1) is done then MDB will open elf but on parsing of elf's debug
info it will refuse to process due to debug info it cannot understand
(symbols with PIE relocation).

Even though it could be done manually (I got it documented quite a while
ago here http://www.denx.de/wiki/U-Boot/ARCNotes) having this automated
way is very convenient. User may build U-Boot that will be loaded on
target via MDB saying "make mdbtrick".

Then if we now apply the manipulation MDB will happily start and will
load all required sections into the target.

Indeed there will be no source-level debug info available. But still MDB
will do its work on showing disassembly, global symbols, registers,
accessing low-level debug facilities etc.

As a summary - this is a pretty dirty hack but it simplifies life a lot
for us ARc developers.

It looks like the increased size of U-Boot lead to a situation
where the boot ROM overwrote its own stack/heap while loading
U-Boot from the SD-card to the SRAM. However, U-Boot worked fine
when loaded through USB serial loader directly into SRAM. It
looks like loading from SD-card uses other stack/heap location
then the serial loader (or maybe no stack or heap at all).
This fix moves U-Boot to gfxRAM, which is 512kB in size and is not

qspi:fsl implement AHB read

The QSPI controller in i.MX 6SoloX and Vybrid supports reading data using

The original driver only supports reading data from IP interface. The IC

we can directly memcpy, a "missed" access to the buffer will cause the
controller to clear the buffer and use the SEQID stored in bfgencr register

Since AHB bus is 64 bit width, we can not set MCR register using 32bit. In
order to minimize code change, redefine QSPI_MCR_END_CFD_LE to 64bit Little
endian but not 32bit Little endia.

Introduce a new configuration option CONFIG_SYS_FSL_QSPI_AHB. If want to

Actually if Vybrid is migrated to use AHB read, this option can be removed and
IP read function can be discared. The reason to introduce this option
is that only i.MX SOC is tested in my side, no Vybrid platform for me.

In spi_setup_slave, the original piece code to set AHB is deleted, since

1) There is an off-by-one in dws->fifo_len setting because it assumes the latest

   to test fifo == 257. In the case fifo is 257, it means the latest valid
   setting is fifo = 256. So after the for loop iteration, we should check
   fifo == 2 case instead of fifo == 257 if detecting the FIFO depth fails.
