Changes from v1:
The patch series supports WDT, SDMC, SMC, SCU, SLI and INTC for AST2700 SoC.

Test steps:
1. Download openbmc image for AST2700 from
   https://github.com/AspeedTech-BMC/openbmc/releases/tag/v09.00
   https://github.com/AspeedTech-BMC/openbmc/releases/download/v09.00/
   ast2700-default-obmc.tar.gz
2. untar ast2700-default-obmc.tar.gz
   ```
   tar -xf ast2700-default-obmc.tar.gz
   ```
3. Run and the contents of scripts as following
IMGDIR=ast2700-default
UBOOT_SIZE=$(stat --format=%s -L ${IMGDIR}/u-boot-nodtb.bin)
UBOOT_DTB_ADDR=$((0x400000000 + ${UBOOT_SIZE}))

qemu-system-aarch64 -M ast2700-evb -nographic -m 8G\
 -device loader,addr=0x400000000,file=${IMGDIR}/u-boot-nodtb.bin,force-raw=on\
 -device loader,addr=${UBOOT_DTB_ADDR},file=${IMGDIR}/u-boot.dtb,force-raw=on\
 -device loader,addr=0x430000000,file=${IMGDIR}/bl31.bin,force-raw=on\
 -device loader,addr=0x430080000,file=${IMGDIR}/optee/tee-raw.bin,force-raw=on\
 -device loader,addr=0x430000000,cpu-num=0\
 -device loader,addr=0x430000000,cpu-num=1\
 -device loader,addr=0x430000000,cpu-num=2\
 -device loader,addr=0x430000000,cpu-num=3\
 -smp 4\
 -drive file=${IMGDIR}/image-bmc,format=raw,if=mtd\
 -serial mon:stdio\
 -snapshot

Known Issue:
1. QEMU supports ARM Generic Interrupt Controller, version 3(GICv3)
but not support Shared Peripheral Interrupt (SPI), yet.
Added work around in INTC patch to set GICINT132[18]
which was BMC UART interrupt if it received GICINT132, so users are
able to type any key from keyboard to trigger GICINT132 interrupt
until AST2700 boot into login prompt. It is a temporary solution.
If users encounter boot stck and no booting log,
please type any key from keyboard.

2. It is required to add "-m 8G" to set the dram size 8G.
AST2700 dram size calculation is not compatible AST2600.
According to the DDR hardware capacity behavior, if users write the
data at address which is over than the supported size, it would set
the data at address 0.
For example:
a. sdram base address "0x4 00000000"
b. sdram size is 1GiB
The available address range is from "0x4 00000000" to "0x4 40000000".
If users write 0xdeadbeef at address "0x6 00000000", the value of
DRAM address 0 (base address 0x4 00000000) should be 0xdeadbeef.
Please see ast2700_sdrammc_calc_size in
https://github.com/AspeedTech-BMC/u-boot/blob/v00.05.00/drivers/ram/aspeed/
sdram_ast2700.c

It seems we should create a new function instead of aspeed_soc_dram_init
to support AST2700.
