board: Add new Samsung "stemmy" board based on ST-Ericsson U8500
The ST-Ericsson U8500 SoC has been used in mass-production for
some Android smartphones released around 2012.
In particular, Samsung has released more than 5 different
smartphones based on U8500, e.g.
- Samsung Galaxy S III mini (GT-I8190) "golden"
- Samsung Galaxy S Advance (GT-I9070) "janice"
- Samsung Galaxy Xcover 2 (GT-S7710) "skomer"
and a few others.
Mainline Linux has great support for the Ux500 SoC, so these
smartphones can also run Linux mainline quite well.
Unfortunately, the original Samsung bootloader used on these devices
has limitations that prevent booting Linux mainline directly.
It keeps the L2 cache enabled, which causes Linux to crash very early,
shortly after decompressing the kernel.
Using U-Boot allows to circumvent these limitations. We can let the
Samsung bootloader chain-load U-Boot and U-Boot locks the L2 cache
before booting into Linux. U-Boot has several other advantages
- it supports device-trees directly and we are no longer limited to
flashing Android boot images through Samsung's proprietary download
mode.
The Samsung "stemmy" board covers all Samsung devices based on U8500.
Add minimal support for "stemmy". For now only UART is supported but
this will be extended later.

arm: Add support for ST-Ericsson U8500 SoC
The NovaThor U8500 SoC was released by ST-Ericsson in 2011.
It was used for some development boards like the CALAO Systems
Snowball SBC, but mass production was primarily for Android
smartphones like the Samsung Galaxy S III mini.
Previous support for U8500 was removed in
commit 68282f55b846 ("arm: Remove unused ST-Ericsson u8500 arch")
since none of the boards were converted to generic boards
before the deadline.
The new code does not have much in common with the previous code.
I have completely rewritten everything, embracing the Driver Model
and device trees wherever possible.
The U8500 support is a bit more minimal for now - my primary
use case is to use U-Boot as alternative bootloader for some of the
U8500 Samsung smartphones. At the moment U-Boot is chain-loaded from
the original Samsung bootloader. A side effect of this is that we
can (temporarily) get away without implementing some functionality
- e.g. all clocks are already enabled by the original bootloader.
More functionality will be added in future patches.

d90fc9c3de Revert "env: solve compilation error in SPL"
Necessary, but not sufficient conditions to see this are
CONFIG_SPL=y (obviously)
CONFIG_SPL_ENV_SUPPORT=n (so flags.o does not get compiled)
CONFIG_SPL_LIBCOMMON_SUPPORT=y (so env/built-in.o is part of the SPL link)
Now, these are satisfied for e.g. imx6q_logic_defconfig. But that
builds just fine, and spl/u-boot-spl.map lists .data.env_htab among
the discarded (garbage collected) sections. Yet, on our
mpc8309-derived board, we do see the build failure, so perhaps the
linker works a bit differently on ppc than on ARM, or there's yet some
other configuration option needed to observe the break.
This is another attempt at solving it, which also cleans up
env/Makefile a bit: Introduce a def_bool y symbol CONFIG_ENV_SUPPORT
which complements CONFIG_(SPL/TPL)_SUPPORT. Then use
CONFIG_$(SPL_TPL_)ENV_SUPPORT to decide whether to include the five
basic env/*.o files. For attr.o, flags.o and callback.o, this
shouldn't change anything. Also, common.o and env.o still get
unconditionally built for U-boot proper. But for TPL/SPL, those two
are only included if CONFIG_(SPL/TPL)_SUPPORT is set.
Having that symbol should also allow simplifying conditionals such as

arm: K3: Disable ROM configured firewalls
ROM configures certain firewalls based on its usage, which includes
the one in front of boot peripherals. In specific case of boot
peripherals, ROM does not open up the full address space corresponding
to the peripherals. Like in OSPI, ROM only configures the firewall region
for 32 bit address space and mark 64bit address space flash regions
as in-accessible.
When security-cfg is initialized by sysfw, all the non-configured
firewalls are kept in bypass state using a global setting. Since ROM
configured firewalls for certain peripherals, these will not be touched.
So when bootloader touches any of the address space that ROM marked as
in-accessible, system raises a firewall exception causing boot hang.
It would have been ideal if sysfw cleans up the ROM configured boot
peripheral firewalls. Given the memory overhead to store this
information provided by ROM and the boot time increase in re configuring
the firewalls, it is concluded to clean this up in bootloaders.
So disable all the firewalls that ROM doesn't open up the full address
