boot: extlinux: Fix unaligned buffer for reading data from file system
extlinux_read_bootflow() allocates a buffer to read from file system
without any alignment.
But for some block devices which transfer data via DMA, ARCH_DMA_MINALIGN
alignment is required. For example, due to misaligned buffer, the below
boot failure is observed.
=> boot
CACHE: Misaligned operation at range [9efa25f8, 9efa27f8]
CACHE: Misaligned operation at range [9efa25f8, 9efa27f8]
CACHE: Misaligned operation at range [9efa25f8, 9efa27f8]
CACHE: Misaligned operation at range [9efa25f8, 9efa27f8]
** Booting bootflow '[email protected]_1' with extlinux
Ignoring unknown command: �D���D��
Boot failed (err=-14)
Change the buffer alignment to ARCH_DMA_MINALIGN.
