5858b90f50 spl: Move SPL_LDSCRIPT defaults to one place
We want to keep all of the default values for SPL_LDSCRIPT in the same
place both for overall clarity as well as not polluting unrelated config

f6810b749f aspeed/ast2600: Fix SPL linker script
The commit 99e2fbcb69 ("linker_lists: Rename sections to remove .
prefix") changed the name of the linker list sections. As the Aspeed SPL
linker wasn't in the tree yet, it missed the change.

This updates the SPL linker to match arch/arm/cpu/u-boot-spl.lds which
Aspeed was copied from.

c0f4756216 powerpc: mpc85xx: Set TEXT_BASE addresses to real base values
Currently CONFIG_SPL_TEXT_BASE and CONFIG_SYS_TEXT_BASE addresses are
manually increased by 0x1000 due to .bootpg section. This section has size
of 0x1000 bytes and is manually put by linker script before .text section
(and therefore before base address) when CONFIG_SYS_MPC85XX_NO_RESETVEC is
set. Due to this fact lot of other config options are manually increased by
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).

Cleanup handling of .bootpg section when CONFIG_SYS_MPC85XX_NO_RESETVEC is
set. Put .bootpg code directly into .text section and move text base
address to the start of .bootpg code. And finally remove +0x1000 value from
lot of config options. With this removal custom PHDRS is not used anymore,
so remove it too.

After this change entry point would be at CONFIG_SPL_TEXT_BASE and not at
address -0x1000 anymore.

Tested on P2020 board with SPL and proper U-Boot.

CONFIG_TIMER drivers are designed differently that timer is free running up

there is no need to get any additional information from DT in the driver

95b7a8fd12 microblaze: cache: introduce cpuinfo structure
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.

d58c007498 microblaze: Add support for run time relocation
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).

07c052be51 microblaze: Create SYM_ADDR macro to deal with symbols
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.

1918c4166e microblaze: Separate code end substraction
Follow up patch will convert symbol handling that's why it is necessary to
separate logic around symbols to special instruction. It adds 4B for new
instruction but it is worth to do it to have code ready for for full

and 2 via EMIO. First two shares the same MIO lines for PHYs. PL based one
have separate EMIO lines via PL.

Also two USB 3.0 with usb hubs are present. USB phys and USB hubs should
have separate reset line. The first usb0 hub also has USB-SD controller
(usb2244) connected to port 0.

To test compatibility with k26 you can run:

- SFP light
- GEM2/3 TX_CLK fixes
- PMOD/RPI connector fixes

1e578ed20c sandbox: Add support for Address Sanitizer
Add CONFIG_ASAN to build with the Address Sanitizer. This only works
with the sandbox so the config is likewise dependent. The resulting
executable will have ASAN instrumentation, including the leak detector
that can be disabled with the ASAN_OPTIONS environment variable:

   ASAN_OPTIONS=detect_leaks=0 ./u-boot

Since u-boot uses its own dlmalloc, dynamic allocations aren't
automatically instrumented, but stack variables and globals are.

Instrumentation could be added to dlmalloc to poison and unpoison memory
as it is allocated and deallocated, and to introduce redzones between
allocations. Alternatively, the sandbox may be able to play games with
the system allocator and somehow still keep the required memory
abstraction. No effort to address dynamic allocation is made by this
patch.

The config is not yet enabled for any targets by default.

Rename the sections used to implement linker lists so they begin with
'__u_boot_list' rather than '.u_boot_list'. The double underscore at the
start is still distinct from the single underscore used by the symbol
names.

Having a '.' in the section names conflicts with clang's ASAN
instrumentation which tries to add redzones between the linker list
elements, causing expected accesses to fail. However, clang doesn't try
to add redzones to user sections, which are names with all alphanumeric
and underscore characters.

The commit b583348ca8 ("image: fit: Align hash output buffers") places
the hash output buffer at the .bss section. However, AST2600 by default
executes SPL in the NOR flash XIP way. This results in the hash output
cannot be written to the buffer as it is located at the R/X only region.

We need to move the .bss section out of the SPL body to the DRAM space,
where hash output can be written to. This patch includes:
 - Define the .bss section base and size
 - A new SPL linker script is added with a separate .bss region specified
 - Enable CONFIG_SPL_SEPARATE_BSS kconfig option

dependent on any particular board. Switch to using ARCH symbols instead
of TARGET.

This whole function could probably use less ifdefs, but for now just do
a minimal conversion.

f99068a8b1 ARM: dts: ls1021a: update the clockgen node
QorIQ platforms now use different clock bindings. Although we don't use
the device tree for clocks on this platform, it is helpful to sync it
because then the bindings will more closely match Linux. Additionally,
it allows for using more clock fractions (such as platform/4).

This corresponds to Linux commit b6f5e7019391 ("ARM: dts: ls1021a:
update the clockgen node").

7171d99296 stm32mp: stpmic1: remove the debug unit request by debugger
Depending on backup register value, U-Boot SPL maintains the debug unit
powered-on for debugging purpose; only BUCK1 is required for powering
the debug unit, so revert the setting for all the other power lanes,
except BUCK3 that has to be always on.

To be functional this patch requires a modification in the debugger
,openocd for example, to update the STM32MP15 backup register when it is
required to debug SPL after reset. After deeper analysis this behavior
will be never supported in tools so the associated code, will be never
used and the associated code can be removed.
