X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7394447505c466d1b5cc664dcec5b2b68aa59142;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ARM: tegra: add Tegra124 SoC support

Add Tegra124 SoC support that base on CortexA15MP Core. And enable the
SMP function that can re-use the same procedure with Tegra114.
