David Gibson 11738cf01f libfdt: Don't use memcpy to handle unaligned reads on ARM ... 6dcb8ba4 "libfdt: Add helpers for accessing unaligned words" introduced the fdt32_ld() and fdt64_ld() helpers for loading values from the FDT blob which might not be naturally aligned. This matters for ARM, where attempting a plain unaligned load will often cause an exception. However, it seems the memcpy() we used here was surprisingly expensive, making libfdt nearly 6x slower on at least some ARM platforms. This patch takes an alternative approach, using a bunch of 1-byte loads and shifts to implement the helpers. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>		2018-11-22 23:37:07 +11:00
