spl: make SPL and normal u-boot stage use independent SYS_MALLOC_F_LEN

Some platforms have very limited SRAM to run SPL code, so there may
not be the same amount space for a malloc pool before relocation in
the SPL stage as the normal U-Boot stage.

Make SPL and (the full) U-Boot stage use independent SYS_MALLOC_F_LEN,
so the size of pre-relocation malloc pool can be configured memory
space independently.

On ARM v7M, the processor will return to ARM mode when executing blx
instruction with bit 0 of the address == 0. Always set it to 1 to stay in thumb
mode.

At present, it is applied only for raw U-Boot. This patch moves it to just
before booting next image. This way armv7m will be in thumb mode for any image
like raw or image with header like zImage or standard U-Boot.

Add bootstage support to SPL. Also support stashing the timing information
when SPL finishes so that it can be picked up and reported by U-Boot
proper. This provides a full boot time record, excluding only the time
taken by the boot ROM.

spl: add support to booting with ATF

ATF(ARM Trusted Firmware) is used by ARM arch64 SoCs, find more infomation
about ATF at: https://github.com/ARM-software/arm-trusted-firmware

SPL is considered as BL2 in ATF terminology, it needs to load other parts
of ATF binary like BL31, BL32, SCP-BL30, and BL33(U-Boot). And needs to
prepare the parameter for BL31 which including entry and image information
for all other images. Then the SPL handle PC to BL31 with the parameter,
the BL31 will do the rest of work and at last get into U-Boot(BL33).

This patch needs work with patches from Andre for SPL support multi
binary in FIT.

The entry point of bl31 and bl33 are still using hard code because we
still can not get them from the FIT image information.

At present malloc_base/_limit/_ptr are not initialised in spl_init() when

at avoiding overwriting the malloc area set up on some boards by

However if CONFIG_SPL_STACK_R_MALLOC_SIMPLE_LEN is not defined, we now
skip setting up the memory area in spl_init() which is obviously wrong.

To fix this, add a new function spl_early_init() which can be called in
board_init_f().

Revert "armv8: release slave cores from CPU_RELEASE_ADDR"

This reverts commit 8c36e99f211104fd7dcbf0669a35a47ce5e154f5.

There is misunderstanding in commit 8c36e99f2111 ("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.

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).
