[RFC PATCH 0/1] Cache incoherent if re-enabled on Cortex-R(5)

From: Emanuele Ghidoli emanuele.ghidoli@toradex.com

I want to propose this patch cause I experience weird behavior on AM62x Cortex-R U-boot spl. Seem that the stack is "restored" to the time dcache_disable was called. The effect is that the code between dcache_disable and dcache_enable is executed twice, but the second execution runs with wrong function parameters.

Best regards,

Emanuele
