[U-Boot] [PATCH v2 0/4] ls102xa: HYP/non-sec: for ls102xa.
Change for V2: - All the registers are defined as a struct, here use it. - Use CONFIG_PEN_ADDR_BIG_ENDIAN instead of CONFIG_SOC_BIG_ENDIAN.
Xiubo Li (4): ARM: HYP/non-sec: add the pen address byte reverting support. ARM: HYP/non-sec: Fix the ARCH Timer frequency setting. ls102xa: HYP/non-sec: support for ls102xa boards ARM: ls102xa: allow all the peripheral access permissions as R/W.

For some SoCs, the pen address may has different endianness with the CPUs, so this need the byte revertion for it,

For some SoCs, the CONFIG_SYS_CLK_FREQ maybe won't equal the ARCH Timer's frequency.
Here using the CONFIG_TIMER_CLK_FREQ instead if the ARCH Timer's frequency need to config here.

The Central Security Unit (CSU) allows secure world software to change the default access control policies of peripherals/bus slaves, determining which bus masters may access them. This allows peripherals to be separated into distinct security domains. Combined with SMMU configuration of the system masters privileges, these features provide protection against indirect unauthorized access to data.
For now we configure all the peripheral access permissions as R/W.

For now we configure all the peripheral access permissions as R/W.

I see half this set is delegated to you and half to me. If you just give your Acked-by: to patches 3 and 4, I will handle the whole set.
Amicalement,
I will take a closer look tomorrow. Being crazy busy lately.
