Subject: [PATCH] PCI: brcmstb: Fix build on 32bit ARM platforms with
|
|
older compilers
|
|
|
|
commit 73a7a271b3eee7b83f29b13866163776f1cbef89 upstream.
|
|
|
|
Some older compilers have no implementation for the helper for 64-bit
|
|
unsigned division/modulo, so linking pcie-brcmstb driver causes the
|
|
"undefined reference to `__aeabi_uldivmod'" error.
|
|
|
|
*rc_bar2_size is always a power of two, because it is calculated as:
|
|
"1ULL << fls64(entry->res->end - entry->res->start)", so the modulo
|
|
operation in the subsequent check can be replaced by a simple logical
|
|
AND with a proper mask.
