First of all U-Boot is not that performance oriented as real run-time
software like OS or user bare-metal app so we may afford being not super
fast as we only being executed once. That in return allows us to be more
universal and support wider variety of devices.
And looking forward that will significantly reduce maintenance and simplify
support of newer architectures.

It's a very rare if at all existing occasion when ARC CPU template
is used as is w/o any changes - in the end it's a beauty and competitive
advantage of ARC cores to be tailored for a particular use-case - and
so it doesn't make a lot of sense to offer template-based "-mcpu" selection.
Given for each and every platform we end-up adding quite a few more flags
it's logical to move "-mcpu" selection to platform's definition as well
which we exactly do here.

Due to the two-instruction sequence needed to access arbitrary memory
locations, the RISC-V linker aggressively optimises memory accesses and
jumps at link-time. This is called "linker relaxation," and is discussed
in this SiFive article
<https://www.sifive.com/blog/all-aboard-part-3-linker-relaxation-in-riscv-toolchain>.
One of the optimizations in place is to assume that the __global_pointer
symbol is placed in the gp register. To quote the article:
"...The magic __global_pointer$ symbol is defined to point 0x800 bytes
past the start of the .sdata section. The 0x800 magic number allows
signed 12-bit offsets from __global_pointer$ to address symbols at the
start of the .sdata section. The linker assumes that if this symbol is
defined, then the gp register contains that value, which it can then use
to relax accesses to global symbols within that 12-bit range. The
compiler treats the gp register as a constant so it doesn't need to be
saved or restored, which means it is generally only written by _start,
the ELF entry point."
However, U-Boot instead keeps the global data pointer in gp. This causes
memory accesses and jumps optimized to use the gp pointer to fail. To
fix this problem, we undefine the __global_pointer symbol.

There can be different types of interrupt controllers in a system and some

handled using the device tree by adding the interrupt information to
device nodes.
However on x86 devices we have interrupt controllers which are not tied
to any particular device and not really used in U-Boot. These still need
to be inited, so a convenient method is to give each controller a type
and allow a particular controller type to be probed.

The fs segment is only used to get the global data pointer.
If it is accessed beyond sizeof(new_gd->arch.gd_addr), it is a bug.
To specify the byte-granule limit size, drop the G bit, so the
flag field is 0x8093 instead of 0xc093, and set the limit field
to sizeof(new_gd->arch.gd_addr) - 1.

All rockchip platforms support TPL or SPL-based bootloader
in mainline with U-Boot proper as final stage. For each
stage we need to burn the image on to flash with respective
offsets.
This patch creates a single boot image component using
- binman, for arm32 rockchip platforms
- pad_cat, for arm64 rockchip platforms.
This would help users to get rid of burning different
boot stage images.
The new image called 'u-boot-rockchip.bin'
which can burn into flash like:
₹ sudo dd if=u-boot-rockchip.bin of=/dev/sda seek=64
This would support all rockchip platforms, except rk3128

Since commit 067e0b9684 ("sunxi: Allow booting from 128KB SD/eMMC offset")
we support having the SPL loaded from either the traditional 8KB SD
card/eMMC offset, or from the alternative location at 128KB. However the
sector to find the U-Boot image was still hard-coded at compile time,
and had to be adjusted for one of the two choices.
Since we can actually override the function to return the sector offset,
we can just check the boot source byte there to select the proper offset
based on from where the SPL was loaded.
This allows the very same binary image to be loaded from either 128KB or
8KB, with the U-Boot proper image always being located just behind the SPL.

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.

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 68282f55b8 ("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.
