Remove cpu name from the defconfig naming. Because other cpus maybe run on AE350 platform. So only use platfrom name in defconfig naming will be better.

There is no need to expose RISCV_NDS to the Kconfig menu as it is an ax25-specific option. Introduce a dedicated Kconfig option for the cache ops of ax25 platform and use that to guard the cache ops.

ax25-ae350 use CONFIG_OF_BOARD via a2 and CONFIG_SYS_SDRAM_BASE to boot from ram which allow the board to override the fdt address originally. But after this patch riscv: save hart ID and device tree passed by prior boot stage It provide prior_stage_fdt_address which offer a temporary memory address to keep the dtb address passing from loader(gdb) to u-boot with a1. So passing via a2 and CONFIG_SYS_SDRAM_BASE is redundant and can be removed. And it also somehow may corrupted BBL if it was be arranged in CONFIG_SYS_SDRAM_BASE. In board_fdt_blob_setup() When boting from ram: prior_stage_fdt_address will be use to reserved dtb temporarily. When booting from ROM: dtb will be pre-burned in CONFIG_SYS_FDT_BASE, if it is flash base. Or CONFIG_SYS_FDT_BASE maybe a memory map space (NOT RAM or ROM) which is provided by HW.

Add smc_init() to get register base from dts and deal with atfsmc020 controler initialzation job. Write protect is enabled by default. So WP shall be disabled when startup, then cfi flash can be detected and erasing and writing can be executed. Adp-ae3xx and adp-ag101p both do smc initilize job in lowlevel_init.S and get register base fron CONFIG_FTSMC020_BASE. They also can be moved those codes to board stage. Remind them as todo jobs. After that CONFIG_FTSMC020_BASE can be removed. Signed-off-by: Rick Chen <rick@andestech.com> Signed-off-by: Rick Chen <rickchen36@gmail.com> Cc: Greentime Hu <green.hu@gmail.com>

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
Enable CONFIG_OF_BOAD to support delivery dtb to u-boot at run time instead of embedded. There are two methods to delivery dtb. 1 Pass from loader: When u-boot boot from RAM, gdb or loader can pass dtb via a2 to u-boot dynamically. Of course gdb or loader shall be in charge of dtb delivery. 2 Configure CONFIG_SYS_FDT_BASE: It can be configured as RAM or ROM base statically, no mater u-boot boot from RAM or ROM. If it was configured as ROM base, dtb can be burned into ROM(spi flash) by spi driver. Meanwhile remove CONFIG_SKIP_LOWLEVEL_INIT which is useless in nx25-ae250 configuration.
