After more patches code for jumping to _start_cont symbol in flash memory
involved to code with useless mathematical operations. Currently it does:
r3 := CONFIG_SYS_MONITOR_BASE + ABS(_start_cont) - CONFIG_SYS_MONITOR_BASE
jump to r3
Which is equivalent of just:
r3 := ABS(_start_cont)
jump to r3
The purpose of that code is just to jump to _start_code symbol,
independently of program counter. So branch must be done to absolute
address. Trying to write:
ba _start_cont
just cause linker error:
LD u-boot
powerpc-linux-gnuspe-ld.bfd: arch/powerpc/cpu/mpc85xx/start.o: in function `switch_as':
(.bootpg+0x4b8): relocation truncated to fit: R_PPC_ADDR24 against symbol `_start_cont' defined in .text section in arch/powerpc/cpu/mpc85xx/start.o
make: *** [Makefile:1801: u-boot] Error 1
Probably by the fact that absolute address cannot be expressed by 24-bits.
So write the code via mtlr+blr pattern as it was before and load general
purpose register with absolute address of the symbol:
lis r3,_start_cont@h
ori r3,r3,_start_cont@l
mtlr r3
blr
Seems that gcc and gnu ld linker support symbol@h and symbol@l syntax like
number@h and number@l without any problem. And disassembling of compiler
u-boot binary proved that lis+ori instructions are called with numbers
which represent halves of absolute address of _start_cont symbol.

For Rockchip boards with the all rk8xx series PMICs (excluding the
rk808), it is sometimes desirable to not boot whenever the device is
plugged in. An example would be for the Odroid Go Advance.
This provides a configurable option to check the PMIC says it was
powered because of a plug-in event. If the value is 1 and this option
is selected, the device shuts down shortly after printing a message
to console stating the reason why it's shutting down. Powering up the
board with the power button is not affected.

in addition to the ELF data. They are essential information for proper

covered by the TEE or a compact representation of runtime relocation
data when ASLR is enabled.
With OP-TEE 3.8.0 onwards, 'tee.elf' MUST NOT be used and 'tee.bin'
MUST be used instead. Ignoring this recommendation can lead to crashes
as described in [3].

0x1000 value to make correct layout. Note that entry point is not on
CONFIG_SPL_TEXT_BASE (image+0x1000) but it is really on address
CONFIG_SPL_TEXT_BASE-0x1000 (means at the start of the image).

Building the sandbox with NO_SDL=1 resulted in an undefined reference to
'sandbox_sdl_remove_display'. Resolve this by adding a stub

As per design, all input/rx pins should have fast slew rate and 12mA
drive strength. Rest all pins should be slow slew rate and 4mA drive
strength. Fix usb nodes as per this and remove setting of slow slew rate
for all the usb gorup pins.

Move axi timer driver from Microblaze to generic location.
Origin implementation was irq based with counting down timer.
CONFIG_TIMER drivers are designed differently that timer is free running up
timer with automatic reload without any interrupt.
Information about clock rates are find out in timer_pre_probe() that's why
there is no need to get any additional information from DT in the driver
itself (only register offset).

Add a basic CPU driver that retrieves information about the microblaze CPU
core. cpu_ops handlers are implemented so that the "cpu" command can work
properly:

0: cpu@0 MicroBlaze @ 50MHz, Rev: 11.0, FPGA family: zynq7000
U-Boot-mONStR> cpu detail
0: cpu@0 MicroBlaze @ 50MHz, Rev: 11.0, FPGA family: zynq7000
ID = 0, freq = 50 MHz: L1 cache, MMU
Note: cpu_ver_lookup[] and family_string_lookup[] arrays were imported from

Introduce a minimal cpuinfo structure to hold cache related info. The
instruction/data cache size and cache line size are initialized early in
the boot to default Kconfig values. They will be overwritten with data
from PVR/dtb if the microblaze UCLASS_CPU driver is enabled.
The cpuinfo struct was placed in global_data to allow the microblaze
UCLASS_CPU driver to also run before relocation (initialized global data
should be read-only before relocation).
gd_cpuinfo() helper macro was added to avoid volatile
"-Wdiscarded-qualifiers" warnings when using the pointer directly.

All flush_cache() calls in microblaze code are supposed to flush the
entire instruction and data caches, so introduce flush_cache_all()
helper to handle this.
Also, provide implementations for flush_dcache_all() and
invalidate_icache_all() so that icache and dcache u-boot commands can
work.

Microblaze is using NEEDS_MANUAL_RELOC from the beginnging. This is causing
issues with function pointer arrays which need to be updated manually after
relocation. Building code with -fPIC and linking with -pic will remove this
limitation and there is no longer need to run manual update.
By default still old option is enabled but by disabling NEEDS_MANUAL_RELOC
code will be compiled for full relocation.
The patch does couple of things which are connected to each other.
- Define STATIC_RELA dependency to call relocate-rela to fill sections.
- REMAKE_ELF was already enabled but u-boot file can't be used because
sections are empty. relocate-rela will fill them and output file is
u-boot.elf which should be used.
- Add support for full relocation (u-boot.elf)
- Add support for early relocation when u-boot.bin is loaded to different
address then CONFIG_SYS_TEXT_BASE
- Add rela.dyn and dynsym sections
Disabling NEEDS_MANUAL_RELOC U-Boot size increased by 10% of it's original
size (550kB to 608kB).

Symbol handling depends on compilation flags. Right now manual relocation
is used that's why symbols can be referenced just by name and there is no
need to find them out. But when position independent code (PIC) is used
symbols need to be described differently. That's why having one macro
change is easier than changing the whole code.
