5 years agoARM: tegra: implement RAM repair
Bibek Basu [Fri, 22 Jun 2018 19:02:28 +0000 (13:02 -0600)]
ARM: tegra: implement RAM repair

RAM repair has a few pre-requisites:
1) PMIC power supply (rail) enabled.
2) PMC CRAIL power partition powered.
3) Fuse clock active (it's the default).
4) PLLP reshift branch enabled (it's the default, when PLLP is active).

RAM repair also only need run whenever specific partitions are powered
(main SoC and CCPLEX respectively); RAM repair does not need to be
triggered when any other partition changes state.

start_cpu() needs to be re-ordered slightly to match these requirements.
Note that C0NC and CE0 aren't required for RAM repair to
operate, but they also do no harm, so the entire of powerup_cpus() is
moved rather than splitting it up. The call to remove_cpu_resets() is
moved last to ensure that all other actions complete before releasing
reset; since the PMC power partitions are now enabled early, releasing
reset is what causes the CPUs to start executing code, and RAM repair must
complete before the CPU boots.

Note that this commit is the result of squashing a numbmer of commits
in NVIDIA's downstream L4T branch, hence the multiple signoffs below.

add support for it.

Examples of usages:

On the pico-imx7d U-Boot prompt:

=> fastboot 0

On the Linux PC connected via USB:

1. Retrieving the U-Boot version

$ sudo fastboot getvar bootloader-version -i 0x0525
bootloader-version: U-Boot 2018.07-rc1-03888-gde846f9

2. Resetting the board

$ sudo fastboot reboot -i 0x0525
