When !MMU, asm-generic will not define default pgprot_writecombine, so c6x
needs to define it by itself. The related error:
CC [M] fs/pstore/ram_core.o
fs/pstore/ram_core.c: In function 'persistent_ram_vmap':
fs/pstore/ram_core.c:399:10: error: implicit declaration of function 'pgprot_writecombine' [-Werror=implicit-function-declaration]
prot = pgprot_writecombine(PAGE_KERNEL);
^
fs/pstore/ram_core.c:399:8: error: incompatible types when assigning to type 'pgprot_t {aka struct <anonymous>}' from type 'int'
prot = pgprot_writecombine(PAGE_KERNEL);
