add rock-3a m.2 e-key sata dts and defconfig

[pykpkg47]

Added dts for rock-3a which switches m.2 e-key to sata and a defconfig which enables the needed options for sata

Tested with m.2 sata ssd , boot works if first partition(/boot) is vfat

depends on #94 which has to be merged first

Hi @pykpkg47, please add the following configs:

CONFIG_SATA=y
CONFIG_CMD_SATA=y
CONFIG_SYS_SCSI_MAX_SCSI_ID=1
CONFIG_SYS_SCSI_MAX_LUN=1

[nascs]

Hi @pykpkg47, please add the following configs:

CONFIG_SATA=y CONFIG_CMD_SATA=y CONFIG_SYS_SCSI_MAX_SCSI_ID=1 CONFIG_SYS_SCSI_MAX_LUN=1

1. you need open sata driver by the config "CONFIG_SATA=y"
2. "CONFIG_CMD_SATA=y" enables this configuration option, which is beneficial for debugging SATA devices on U-Boot

Hi @pykpkg47, please add the following configs:
CONFIG_SATA=y CONFIG_CMD_SATA=y CONFIG_SYS_SCSI_MAX_SCSI_ID=1 CONFIG_SYS_SCSI_MAX_LUN=1

1. you need open sata driver by the config "CONFIG_SATA=y"
2. "CONFIG_CMD_SATA=y" enables this configuration option, which is beneficial for debugging SATA devices on U-Boot

3. The other two settings are conducive to the more efficient initialization and management of available devices in the system.

[nascs]

Certainly, "CONFIG_CMD_SATA=y" is an optional configuration option.

[pykpkg47]

added the configs , build u-boot without error, will test later on device

[pykpkg47]

Tested with added config options sata boot still works

@pykpkg47

Hi. I can see that there is ^M at the end of each line in file rk3568-rock-3a-sata.dts and rock-3a-sata-rk3568_defconfig.
Please remove the ^M.

[pykpkg47]

done changed carriage returns to Line Feed (though git in vscode does that themself but was wrong)

[RadxaStephen]

Thanks. I see that rock-3a-sata-rk3568_defconfig is correct. Please also modify file dts rk3568-rock-3a-sata.dts.

[RadxaStephen]

Please rewrite these two commits.

1. 464932b

Remove ^M

2. fda58fc

Remove rk3568-rock-3a-sata.dts from this commit since this commit is for rock 3a sata defconfig.

[RadxaStephen]

I rewrite the pr and merge it.

@pykpkg47 Thanks for your great work.
