Most predefined TLB tables don't have memory coherence bit set for SDRAM. This wasn't an issue before invalidate_dcache_range() function was enabled. Without the coherence bit, dcache invalidation doesn't automatically flush the cache. The coherence bit is already set when dynamic TLB table is used. For some boards with different SPL boot method, or with legacy fixed setting, this bit needs to be set in TLB files. Signed-off-by: York Sun <york.sun@nxp.com>
