arm: kirkwood: 88f6281: Detect CONFIG_SYS_TCLK from SAR register
Bit 21 in SAR register specifies if TCLK is running at 166 MHz or 200 MHz.
This information is undocumented in public Marvell Kirkwood Functional
Specifications [2], but is available in Linux v3.15 kirkwood code [1].
Commit
8ac303d49f89 ("arm: kirkwood: Do not overwrite CONFIG_SYS_TCLK")
broke support for Marvell 88F6281 SoCs because it was expected that all
those SoCs have TCLK running at 200 MHz as specified in Marvell 88F6281
Hardware Specifications [3].
Fix broken support for 88F6281 by detecting CONFIG_SYS_TCLK from SAR
register, like it was doing Linux v3.15.

time: move the CONFIG_SYS_TIMER_RATE handling to the compiler
CONFIG_SYS_TIMER_RATE might be a dynamic value, i.e. a function call
instead of a static value, thus it has to be evaluated at runtime. If it
is a static value, the compiler should be able to optimize the unused
branches out.
This will be needed for kirkwoods dynamic CONFIG_SYS_TCLK setting.

arm: mvebu: mbus: Fix mbus driver to work also after U-Boot relocation
mbus driver is initialized from arch_cpu_init() callback which is called
before relocation. This driver stores lot of functions and structure
pointers into global variables, so it is data position dependent.
Therefore after relocations all pointers are invalid and driver does not
work anymore as all pointers referes to the old memory, which overlaps with
CONFIG_SYS_LOAD_ADDR and ${loadaddr}.
For example U-Boot fuse command crashes if loadaddr memory is cleared or
rewritten by some image loaded by U-Boot load command.
mw.w ${loadaddr} 0x0 10000
fuse read 0 1 2
Fix this issue by removing of all mbus global variables in which are stored
pointers to structures or functions which changes during relocation. And
replace it by direct function calls (not via pointers). With this change
fuse command finally works.

binman: Add length header attribute to dtb entry
Add an optional length header attribute to the device tree blob entry
class based on the compressed data header from the utilities to compress
and decompress data.
If needed the header could be enabled with the following
attribute beside the compress attribute:
prepend = "length";
The header was introduced as part of commit
eb0f4a4cb402 ("binman:
Support replacing data in a cbfs") to allow device tree entries to be
larger than the compressed contents. Regarding the commit "this is
necessary to cope with a compressed device tree being updated in such a

case)". This case need to be fixed without influence any compressed data

arm64: explicitly disable pointer authentication instructions
The Yocto project builds their aarch64 cross-compiler with the
configure knob --enable-standard-branch-protection, which means that
their gcc behaves as if -mbranch-protection=standard is passed; the
default (lacking that configure knob) is -mbranch-protection=none.
This means that when building U-Boot using the Yocto toolchain, most
functions end up containing paciasp/autiasp/bti instructions. However,
since U-Boot is not an ordinary userspace application, there's no OS
kernel which has set up the required authentication keys, so these
instructions do nothing at all (even on arm64 hardware that does have
the pointer authentication capability). They do however make the image
larger.
It is theoretically possible for U-Boot to make use of the pointer
authentication protection - cf. the linux kernel's
CONFIG_ARM64_PTR_AUTH_KERNEL - but it is far from trivial, and it's
hard to see just what threat model it would protect against in a
bootloader context. Regardless, we certainly have none of the required
infrastructure now, so explicitly pass -mbranch-protection=none to
ensure those useless instructions do not get emitted.
For a toolchain not configured with
--enable-standard-branch-protection, this changes nothing. For the
Yocto toolchain, this reduces the size of both SPL and U-Boot proper
by about 3% for my imx8mp target.
If you don't have a Yocto toolchain, the effect can easily be
reproduced by applying this patch and changing =none to =standard.
