6bda55a38c x86: Do relocation before clearing BSS
The BSS region may overlap with relocations. If we clear BSS we will
overwrite the start of the relocation area. This doesn't matter when running
from SPI flash, since it is read-only. But when relocating 64-bit U-Boot
from one place in RAM to another, relocation will fail because some of its
relocations have been zeroed.

To fix this, put the ELF fixup call before the BSS clearing call.

fb92308b98 x86: board_r: Set the global data pointer after relocation
Since 'gd' is just a normal variable on 64-bit x86, it is relocated by the
time we get to board_init_r(). The old 'gd' variable is passed in as
parameter to board_init_r(), presumably for this situation.

Assign it on 64-bit x86 so that gd points to the correct data.

Options to improve this:
- Make gd a fixed register and remove the board_init_r() parameter
- Make all archs use this board_init_r() parameter

The second has a TODO in the code. The first has a TODO in a future commit
('x86: Support global_data on x86_64')

c0efc3140e ARM: uniphier: change CONFIG_SPL_PAD_TO to 128KB
The Boot ROM supports authentication feature to prevent malformed
software from being run on products.  The signature is added at the
tail of the second stage loader (= SPL in U-boot terminology).

The size of the second stage loader was 64KB, and it was consistent
across SoCs.  The situation changed when LD20 SoC appeared; it loads
80KB second stage loader, and it is the only exception.

Currently, CONFIG_SPL_PAD_TO is set to 64KB and U-Boot proper is
loaded from the 64KB offset of non-volatile devices.  This means the
signature of LD20 SoC (located at 80KB offset) corrupts the U-Boot
proper image.

Let's move the U-Boot proper image to 128KB offset.  It uses 48KB
for nothing but padding, and we could actually locate the U-Boot
proper at 80KB offset.  However, the power of 2 generally seems a
better choice for the offset address.

7b74c4b60b Revert "armv8: release slave cores from CPU_RELEASE_ADDR"
This reverts commit 8c36e99f21.

There is misunderstanding in commit 8c36e99f21 ("armv8: release
slave cores from CPU_RELEASE_ADDR").  How to bring the slave cores
into U-Boot proper is platform-specific.  So, it should be cared
in SoC/board files instead of common/spl/spl.c.  As you see SPL
is the acronym of Secondary Program Loader, there is generally
something that runs before SPL (the First one is usually Boot ROM).

How to wake up slave cores from the Boot ROM is really SoC specific.
So, the intention for the spin table support is to bring the slave
cores into U-Boot proper in an SoC specific manner.  (this must be
done after relocation.  see below.)

If you bring the slaves into SPL, it is SoC own code responsibility
to transfer them to U-Boot proper.  The Spin Table defines the
interface between a boot-loader and Linux kernel.  It is unrelated
to the interface between SPL and U-Boot proper.

One more thing is missing in the commit; spl_image->entry_point
points to the entry address of U-Boot *before* relocation.  U-Boot
relocates itself between board_init_f() and board_init_r().  This
means the master CPU sees the different copy of the spin code than
the slave CPUs enter.  The spin_table_update_dt() protects the code
*after* relocation.  As a result, the slave CPUs spin in unprotected
code, which leads to unstable behavior.

c2e7e72bb9 bootm: relocate ramdisk if CONFIG_SYS_BOOT_RAMDISK_HIGH set
In 35fc84f, bootm was refactored so plain 'bootm' and
'bootm <subcommand>' shared a common implementation.
The 'bootm ramdisk' command implementation is now part of the common
implementation but not invoke by plain 'bootm' since the original
implementation never did ramdisk relocation.  Instead, ramdisk
relocation happened in image_setup_linux() which is typically called
during the OS portion of 'bootm'.

On ARM, parameters to the Linux kernel can either be passed by FDT or
ATAGS. When using FDT, image_setup_linux() is called which also triggers
ramdisk relocation.  When using ATAGS, image_setup_linux() is _not_
called because it mostly does FDT setup.

Instead of calling image_setup_linux() in both FDT and ATAGS cases,
include BOOTM_STATE_RAMDISK in the requested states during a plain
'bootm' if CONFIG_SYS_BOOT_RAMDISK_HIGH is set and remove the ramdisk
relocation from image_setup_linux().  This causes ramdisk relocation to
happen on any system where CONFIG_SYS_BOOT_RAMDISK_HIGH regardless of
the OS being booted. Also remove IMAGE_ENABLE_RAMDISK_HIGH as it was
only used by the now-removed code from image_setup_linux().

8c36e99f21 armv8: release slave cores from CPU_RELEASE_ADDR
When using ARMv8 with ARMV8_SPIN_TABLE=y, we want the slave cores to
wait on spin_table_cpu_release_addr, until the Linux kernel will "wake" them
by writing to that location. The address of spin_table_cpu_release_addr is
transferred to the kernel using the device tree that is updated by
spin_table_update_dt().

However, if we also use SPL, then the slave cores are stuck at
CPU_RELEASE_ADDR instead and as a result, never wake up.

This patch releases the slave cores by writing spl_image->entry_point to
CPU_RELEASE_ADDR location before the end of the SPL code
(at jump_to_image_no_args()).

That way, the slave cores will start to execute the u-boot and will get to
the spin-table code and wait on the correct address
(spin_table_cpu_release_addr).
