Some chips provide their sysreset function in reset controller, which is
normally a bit written to 1 to perform the sysreset.
This patch adds a new sysreset driver to take advantage of it.

This patch adds a MIPS specific jump_to_image_no_args() implementation,
which flushes the U-Boot proper image loaded from the boot device in
SPL before jumping to it.
It has been noticed on MT76x8, that this cache flush is needed. Other
MIPS platforms might need it as well.

u_boot_list is not only used by DM, but also by some SPL image load methods
such as spl_nor.c.
This patch adds an option CONFIG_SPL_LOADER_SUPPORT in conjunction with
CONFIG_SPL_DM surrounding the u_boot_list section to make sure SPL image
loaders can be correctly built into u-boot SPL without DM enabled.

If CONFIG_SPL_OF_CONTROL is enabled for SPL and CONFIG_OF_SEPARATE is also
enabled, the dtb will be appended to the u-boot-spl.bin.
When calling dm_init_and_scan() in SPL, fdtdec_setup() will try to locate
dtb at the end of u-boot-spl.bin, by referencing to _image_binary_end.
However _image_binary_end is currently missing in u-boot-spl.lds.
This patch adds _image_binary_end to u-boot-spl.lds to make sure linking
u-boot-spl will not fail.

When setting up initial stack, global data will also be put in the stack,
and being cleared.
The assembler instructions for clearing gd is as follows:
move t0, k0
1:
PTR_S zero, 0(t0)
blt t0, t1, 1b
PTR_ADDIU t0, PTRSIZE
t0 is the start address of gd, t1 is the end address of gd (t0 + GD_SIZE).
[PTR_ADDIU t0, PTRSIZE] is in the delay slot of [blt t0, t1, 1b], so it
will be executed before the branch operation.
However the comparison for the BLT instruction is done before executing the
delay slot. This means when the last word just before k1 is cleared, the
loop will continue to run once. This will clear an extra word at k1, which
is outside the global data.
Global data is placed at the top of the stack. If the initial stack is a
SRAM or locked cache, the area outside them may be inaccessible. A write
operation performed in this area may cause an exception.
To solve this, [PTR_ADDIU t0, PTRSIZE] should be placed before the BLT
instruction.

In U-Boot the exception vector base will be moved to top of memory, to be

But some old linux kernel does not honor the base set in CP0_EBASE. A
