4257ea4efd Blackfin: post: drop custom test list
The few tests that are Blackfin-specific have been migrated to common
code or been rewritten with the existing "bsp-specific" defines.

226502e01b ppc4xx: Flush dcache after DDR2 autocalibration with caches on
Flush the dcache before removing the TLB with caches enabled.
Otherwise this might lead to problems later on, e.g. while booting
Linux (as seen on ICON-440SPe).

025bc4254b omap4: make SDRAM init work for ES1.0 silicon
SDRAM init was not working on ES1.0 due to a programming
error. A pointer that was passed by value to a function
was set in function emif_get_device_details(), but the effect
wouldn't be seen in the calling function. The issue came
out while testing for ES1.0 because ES1.0 doesn't have any
SDRAM chips connected to CS1

81bdc155c7 omap: gpio: Use generic API
Convert all OMAP specific functions to use the common API
definitions in include/asm/gpio.h. In the process, made
few additional changes:
 - Use -EINVAL consistently. -1 was used in many places.
 - Removed one-liner static functions that were used only
   once. Replaced the content as necessary.
 - Combines implementation of functions omap_get_gpio_dataout()
   and omap_get_gpio_datain(). To do so, new static function
   _get_gpio_direction() was added.

99ffccbd3e Flush cache after the OS image is loaded into the memory.
Since we are loading an executable image into memory we need flush it
out of the cache to possible maintain coherence on CPUs with split
instruction and data caches.  We do this for other executable image
loading command.

On PowerPC once we do this we no longer need to explicitly flush the
dcache on multi-core systems in the BOOTM_STATE_OS_PREP phase.  We now
treat the BOOTM_STATE_OS_PREP as a no-op to maintain backwards
compatibility with the bootm subcommand.

AM/DM37x is another OMAP3 variant, where the GFX clock has been
boosted to 192MHz/200MHz. So fix the GFX_DIV value for this change.

HW Errata: Due to dependency of TV out clock of 54MHz, it is not
possible to configure GFX to 192MHz. So as per HW errats, the
recommended GFX clock is 200MHz (=CORE_CLK/2).

7acec25948 MX: MX35 / MX5: uniform clock command with powerpc
There was already a command to show the processor clocks
for PowerPC (clocks). For i.MX, the "clockinfo" command
was introduce. The patch sets the same command name used on
PowerPC.
A nasty and not needed newline is also dropped in the help for
the command.

9db1bfa110 ARM: MX51: PLL errata workaround
This is a port of the official PLL errata workaround from Freescale to
mainline u-boot.
The PLL's in the i.MX51 processor can go out of lock due to a metastable
condition in an analog flip-flop when used at high frequencies.
This workaround implements an undocumented feature in the PLL (dither
mode), which causes the effect of this failure to be much lower (in terms
of frequency deviation), avoiding system failure, or at least decreasing
the likelihood of system failure.
