Revision	Date	Author	Comments
1.7	24-Apr-2022	mlelstv	Use physical sector size as unit for disk addresses. Provide new ioctl to libsa to query for sector size.
1.6	21-Jun-2021	jmcneill	efiboot: Add readahead support. Reading data through libsa file-systems ends up breaking block I/O accesses into very small (512-byte or 2048-byte) accesses. This can be very inefficient, and causes Ampere eMAG w/ BMC image direction to take _minutes_ to load the install image and kernel. So slow in fact that the default watchdog timeout will fire before it finishes. So, when loading big files, optimistically read ahead up to 64KB of data. Brings the time to boot the install ISO down to around 40 seconds -- still not ideal but way better than before.
1.5	21-Jun-2021	jmcneill	efiboot: Use disk I/O protocol for block device access. EFI_DISK_IO_PROTOCOL is a simplified interface to block devices. Use this instead of EFI_BLOCK_IO_PROTOCOL for accessing block devices to simplify the code -- we no longer need to worry about the underlying media's block I/O size and alignment requirements.
1.4	11-Oct-2020	jmcneill	branches: 1.4.6; Add ISO9660 support.
1.3	01-Nov-2018	jmcneill	branches: 1.3.4; Add GPT support.
1.2	27-Aug-2018	jmcneill	branches: 1.2.2; Pass a hash of the MBR and the booted partition to the kernel.
1.1	26-Aug-2018	jmcneill	Add support for booting kernels from FFS partitions.
