Allow tagging variables with __nocach_noinit. With CONFIG_NOCACHE_MEMORY=y, this will resolve to __nocache, which implies __noinit. With CONFIG_NOCACHE_MEMORY=n, this simply resolves to __noinit. Signed-off-by: Henrik Brix Andersen <[email protected]> (cherry picked from commit afe1ca6)
Use __nocache_noinit for the Bosch M_CAN MRAM data variables on SoCs without dedicated MRAM. Fixes: #64691 Signed-off-by: Henrik Brix Andersen <[email protected]> (cherry picked from commit 58e1963)
