Subject: stm32mp1: ram: add pattern parameter in infinite write test
X-Git-Tag: v2019.10-rc4~31^2~16
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=757bca8d196fee46d84ee07e0ab220d4992d9dd9;p=platform%2Fkernel%2Fu-boot.git

stm32mp1: ram: add pattern parameter in infinite write test

Add pattern for infinite test_read and test_write, that
allow to change the pattern to test without recompilation;
default pattern is 0xA5A5AA55.
