This patch series imports device tree include files for comaptibility
with P2020 device tree files from upstream Linux kernel. So it allows to
share same P2020 board device tree files between Linux kernel and U-Boot.
Pali Rohár (2):
powerpc: dts: p2020: Add fsl/p2020si-pre.dtsi and
fsl/p2020
Import pq3-duart-0.dtsi device tree include file from upstream Linux kernel
for P2020. This allows U-Boot to use P2020 device tree files from upstream
Linux kernel which reference serial0 or serial1 devices.

If env is stored on SD card then U-Boot SPL automatically calls mmc_init()
before it is going to load proper U-Boot from SD card.
If env is not stored on SD card then U-Boot SPL fails to read proper U-Boot
from SD card due to missing mmc_init() call.
So add missing mmc_init() call into fsl_esdhc_
In pre-PBL header is stored size of code which BootROM copies from SD card
to L2/SRAM. This size has upper limit of L2 cache size. In most cases this
is size of U-Boot SPL or size of L2 cache.
Therefore this size in pre-PBL header cannot be used for determining size
of proper U-Boot.
So always us
This patch series contains fixes which makes SPL running on P2020 board
to load proper U-Boot from SD card with non-default or non-common
configuration. Tested on P2020 based board.
Pali Rohár (3):
mmc: fsl_esdhc_spl: pre-PBL: check for BOOT signature instead of

mmc: fsl_esdhc_spl:

P1021, P1022) require custom BOOT signature on sector 0 and MBR/DBR
signature is not required at all.
So add check for BOOT signature and remove check for MBR/DBR.
This allows U-Boot SPL to load proper U-Boot on pre-PBL Boot

This patch series cleanups mpc85xx e500 code. It removes _start symbol
together with its content because it is useless and then rename symbol
_start_e500 to _start as this is the real entry point. Third patch just
show e500 core version.
Tested on P2020 board with configuration when BootROM loads
_start symbol contains only 32-bit data number 0x27051956 despite it is
marked as text section. This magic number is IH_MAGIC which is used for
marking uboot image header.
mpc85xx start.S code does not define valid uboot image header, so IH_MAGIC
number in _start symbol is useless there.
Moreover
While running tests for a python tool, the tests' outputs get printed in
whatever order they happen to run, without any indication as to which
output belongs to which test. Unittest supports capturing these outputs
and printing them as part of the test summaries, but when a failure or
error occurs
The python tools' test utilities handle printing test results, but the
output is quite bare compared to an ordinary unittest run. Delegate
printing the results to a unittest text runner, which gives us niceties
like clear separation between each test's result and how long it took to
run the test su
By default, unittest test summaries only print extended info about tests
that failed or couldn't run due to an error. Use a custom text result
class to print info about more cases: skipped tests, expected failures
and unexpected successes.

It's possible to request a specific test to run when trying to run a

When printing a python tool's test results, the entire list of failed
