Sascha Hauer c3995e85d2 ARM: tqma53: call SoC lowlevel function early
With CONFIG_MMU_EARLY enabled the board does not survive the call
to imx53_init_lowlevel(). This should not happen, but the reasons
are currently unknown. This works on other boards like the i.MX53
QSB.
This patch moves the call to imx53_init_lowlevel to
barebox_arm_reset_vector() which is executed with MMU disabled.

Sascha Hauer 17ad33b5d5 ARM: i.MX53: split lowlevel function into early/nonearly version
clock_notifier_call_chain() can't be called before init time. Protecting
it with IS_ENABLED(__PBL__) is not enough. This patch splits out a new
imx53_init_lowlevel_early which can be called before init time and does
not have the call to clock_notifier_call_chain() in it.

Sascha Hauer 389785f106 ARM: i.MX53: Fix pll216 setup
The value for i.MX53 216MHz is actually 432MHz. Use the same value
as for i.MX51 which really corresponds to 216MHz. These are the same
PLL216 values as U-Boot uses.

Rename the barebox_loc environment variable to bootsource, since
- barebox_loc is a mixture between abbriviation and fulltext which is not nice
- technically it describes the source the SoC has booted from. This is not
  necessarily barebox but could also be some other first stage loader.

Steffen Trumtrar 26121ef51d ARM: zynq: add zynq fsbl checksum script
The bootrom only reads an image if the correct checksum is present in the
header. The calculation is pretty simple:
sum over all words from 0x20 to 0x44
Two of this words are the image length. That is why the checksum can not be
calculated until barebox_image_size is known.
The easiest solution is a program that has to be run after make.

On some i.MX SoCs the SDRAM controller has chipselect 2 enabled
by reset default. This confuses our SDRAM size detection. We
already have a fix for this in place. This patch adds the fix
for i.MX35 which needs it aswell. Also since we now detect the
SDRAM size in the SoC specific entry functions we have to apply
the fixup there, too.
