Subject: cfi_flash: Use u8 pointers instead of void pointers
X-Git-Url: http://git.dujemihanovic.xyz/img/static/git-favicon.png?a=commitdiff_plain;h=5312838dd5b3959907d6c4f0ec3e04954210fafc;p=u-boot.git

cfi_flash: Use u8 pointers instead of void pointers

According to the C standard, pointer arithmetic for pointers of type
void is undefined behavior (the assumption that they're 8-bit wide is a
GCC-specific assumption). In the interest of keeping the code
standards-compliant, and also better communicate intent, switch all
void* variables where pointer arithmetic is used to u8* variables.
