46  * is 32 bits not 8 bits like our guid_t. In some cases (i.e., on 32-bit ARM),
48  * efi_guid_t* arguments are 32-bit aligned, and use memory accessors that
49  * do not tolerate misalignment. So let's set the minimum alignment to 32 bits.
52  * suggest that EFI_GUID should be 64-bit aligned, but this appears to be
53  * a mistake, given that no code seems to exist that actually enforces that
