ff6d1948dc mips: mt7628: fix the displayed DDR type of mt7628
The MT7688KN is a multi-chip package with 8MiB DDR1 KGD. So the DDR type
from bootstrap register must be ignored, and always be assumed as DDR1.

This patch fixes the displayed DDR type of mt7628.

a9961e5acd mips: mt7628: fix ddr_type for MT7688KN
The MT7688KN is a multi-chip package with 8MiB DDR1 KGD. So the DDR type
from bootstrap register must be ignored, and always be assumed as DDR1.

This patch fixes an issue that mt7628_ddr_pad_ldo_config() may be passed
with a wrong ddr_type in MT7688KN.

401d1c4f5d common: Drop asm/global_data.h from common header
Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

451abbbedd mips: mtmips: move mt7628 related Kconfig into mt7628 subdirectory
This patch is a preparation for add a new soc fot mtmips.

Move all mt7628 related Kconfig (boards and UART selection) into mt7628
subdirectory and make sure the top directory of mtmips contains only
selection for SoCs.

65e25bea59 dm: Rename DM_GET_DRIVER() to DM_DRIVER_GET()
In the spirit of using the same base name for all of these related macros,
rename this to have the operation at the end. This is not widely used so
the impact is fairly small.

7a4b6964b5 mips: mtmips: add SPL support
This patch adds SPL support for mtmips platform. The lowlevel architecture
is split into SPL and the rest parts are built into a memory loadable
u-boot image. Optional SPL_DM and OF_CONTROL are also supported.

The increment of size is very small (< 10 KiB) if SPL_DM and OF_CONTROL are
not enabled and the memory bootable u-boot (u-boot.img) is generated
automatically so there is not need to add a separate config for it.

A lzma compressed payload (u-boot-lzma.img) is also generated and it will
be combined with u-boot-spl.bin to form the unified ROM bootable binary
u-boot-mtmips.bin.

A spl loader is added to support uncompress the payload.

02cd449f0b mips: mtmips: rewrite lowlevel codes of mt7628
This patch rewrites the mtmips architecture with the following changes:

1. Move MT7628 soc parts into a subfolder.
2. Lock parts of D-Cache as temporary stack.
3. Reimplement DDR initialization in C language.
4. Reimplement DDR calibration in a clear logic.
5. Add full support for auto size detection for DDR1 and DDR2.
6. Use accurate CPU clock depending on the input xtal frequency for timer
   and delay functions.

Note:

print_cpuinfo() has incompatible parts with MT7620 so it's moved into
mt7628 subfolder.
