[PATCH v3 0/3] Add SPL build support for RK3568

[PATCH v3 0/3] Add SPL build support for RK3568

[Nico Cheng]

This series adds support for the rk3568 SOC, SPL load next-stage image from
eMMC will be supported after this series of patches.

Changes in v3:
Replace configuration parameters of SGRF_SOC_CON4 with macro
definitions.

Changes in v2:
We use the rk_clrreg function instead of the writel to set eMMC sdmmc0 to
secure.
Modify comments to make them more explicit.

[PATCH v3 3/3] rockchip: rk3568: add arch_cpu_init()

[Nico Cheng]

We configured the drive strength and security of EMMC in
arch_cpu_init().

Signed-off-by: Nico Cheng <nico.cheng@rock-chips.com>

Changes in v3:
Replace configuration parameters of SGRF_SOC_CON4 with macro
definitions.

Changes in v2:
We use the rk_clrreg function instead of the writel to set eMMC sdmmc0 to
secure.
Modify comments to make them more explicit.

Re: [PATCH v3 0/3] Add SPL build support for RK3568

Hi Nico,

Is this expected to work with Arm Trusted Firmware or some other TF?

Could we have some docs/details for how to test this?

Re: [PATCH v3 0/3] Add SPL build support for RK3568

[Kever Yang]

Hi Peter,

     This add SPL support for RK3568, and the ATF support is a function 
support int the ATF in rockchip platform, so if this chip works, them it 
will of course support ATF like other rockchip SoCs.

Thanks,
