riscv: ax25-ae350: Use generic memory size setup

2019-12-10T00:23:10+00:00

To get memory size from device tree instead of
get_ram_size(). This can avoid memory access fault
in U-Boot proper after PMP configurations in OpenSBI.

riscv: ax25-ae350: add SPL configuration

2019-12-10T00:23:10+00:00

This patch provides four configurations which can support U-Boot SPL
to boot from RAM or FLASH and then boot FIT image including OpenSBI
FW_DYNAMIC firmware and U-Boot proper images from RAM or MMC boot devices.

With ae350_rv[32|64]_spl_defconfigs:

U-Boot SPL will be loaded by gdb or FSBL and runs in RAM in machine mode
and then load FIT image from RAM device on AE350.

With ae350_rv[32|64]_spl_xip_defconfigs:

U-Boot SPL can be burned into SPI flash and run in flash in machine mode
and then load FIT image from SPI flash or MMC device on AE350.

riscv: configs: AE350 will use CONFIG_OF_SEPARATE when boots from flash

2019-05-09T08:46:46+00:00

When AE350 boots from flash, use CONFIG_OF_SEPARATE instead of
CONFIG_OF_BOARD.

Also remove unused code about prior_stage_fdt_address.
And modify CONFIG_SYS_FDT_BASE as flash address.

riscv: configs: Rename ax25-ae350 defconfig

2018-12-18T05:25:55+00:00

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.

Also sync MAINTAINERS:
Rename
a25-ae350_32_defconfig as ae350_rv32_defconfig
ax25-ae350_64_defconfig as ae350_rv64_defconfig

riscv: ax25: Hide the ax25-specific Kconfig option

2018-12-18T01:56:26+00:00

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.

riscv: ax25-ae350: Pass dtb address to u-boot with a1 register

2018-12-05T06:14:16+00:00

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.
