Subject: Tegra: enable 'WARMBOOT_ENABLE_DCACHE_EARLY' flag
X-Git-Url: http://git.openwrt.org/%22https:/collectd.org//%22/%22https:/collectd.org/%22?a=commitdiff_plain;h=fda818c9472873a747a72bb34a23c29a576e898c;p=project%2Fbcm63xx%2Fatf.git

Tegra: enable 'WARMBOOT_ENABLE_DCACHE_EARLY' flag

This patch enables the 'WARMBOOT_ENABLE_DCACHE_EARLY' flag to enable
D-cache early, during the CPU warmboot sequence. This flag is applicable
for platforms like Tegra, which do not require interconnect programming to
enable cache coherency.
