6 years agosf: Set current flash bank to 0 in clean_bar()
Marek Vasut [Thu, 24 May 2018 19:58:40 +0000 (21:58 +0200)]
sf: Set current flash bank to 0 in clean_bar()

The clean_bar() function resets the SPI NOR BAR register to 0, but
does not set the flash->curr_bar to 0 , therefore those two can get
out of sync, which could ultimatelly result in corrupted flash content.

The simplest test case is this:

  => mw 0x10000000 0x1234abcd 0x4000
  => sf probe
  => sf erase 0x1000000 0x10000
  => sf write 0x10000000 0x1000000 0x10000

  => sf probe ; sf read 0x12000000 0 0x10000 ; md 0x12000000

That is, erase a sector above the 16 MiB boundary and write it with
random pre-configured data. What will actually happen without this
patch is the sector will be erased, but the data will be written to
BAR 0 offset 0x0 in the flash.

This is because the erase command will call write_bar()+clean_bar(),
which will leave flash->bank_curr = 1 while the hardware BAR registers
will be set to 0 through clean_bar(). The subsequent write will also
trigger write_bar()+clean_bar(), but write_bar checks if the target
bank == flash->bank_curr and if so, does NOT reconfigure the BAR in
the SPI NOR. Since flash->bank_curr is still 1 and out of sync with
the HW, the condition matches, BAR programming is skipped and write
ends up at address 0x0, thus corrupting flash content.

The current coding advances the column by the number of UTF-8 bytes.
The column should be increased by one per unicode character.

The UEFI spec provides advance rules for U+0000, U+0008, U+000A,

Merge tag 'arc-updates-for-2018.07-rc1' of git://git.denx.de/u-boot-arc

Here we do a couple of minor fixes like:
 - Move .ivt section to the very beginning of the image
   by default which allows us to use that image put right
   at reset vector (usually 0x0)

 - Improve relocation fix-up which became required once
   we moved .ivt and understood a problem with existing implementation
   where we relied on a particular placement of sections.
   Now we don't care about placement because we just explicitly
   check for .text and in case of ARCompact .ivt sections

 - Re-implemnt do_reset() such that it calls reset_cpu() which
   could implmented for a particular board

And hte most important part we introduce support for yet another
devboard from Synopsys - EMDK.

ARC: Improve relocation fix-ups

We used to have the one and only linker script for all ARC boards
and so we relied on a particular order of symbols there.

Because of that we used __ivt_end as the marker of the end of all the
code which won't be true any longer if we move .ivt section to any other
place. That said we'd better check for each section separately.

A couple of other improvements:
 1. There's no point to include the marker of section end in interested
    range because its address is beyond the section, i.e. we should
    compare with "<" but not "<=".

 2. .ivt section for ARCv2 cores is just an array of 32-bit ints and
    they are not swapped even on little-endia cores while in case of
    ARCompact cores .ivt contains valid code so swapping is required.

 3. Just in case add check for ARC600 which is also ARCompact
    and its .ivt is normal code.
