Revision	Date	Author	Comments
1.20	14-Jun-2023	rin	Avoid void * pointer arithmetic; cast to UINT8 * explicitly. No binary changes for aarch64 at least.
1.19	24-Apr-2022	mlelstv	branches: 1.19.4; Use physical sector size as unit for disk addresses. Provide new ioctl to libsa to query for sector size.
1.18	30-Oct-2021	jmcneill	If a path is not specified, assume /. This makes "ls" and "ls hd0b:" work as expected.
1.17	23-Jun-2021	jmcneill	fix typo
1.16	23-Jun-2021	jmcneill	Fix buffer size for alignment adjusted block I/O reads.
1.15	22-Jun-2021	jmcneill	efiboot: Use EFI_BLOCK_IO_PROTOCOL if EFI_DISK_IO_PROTOCOL is missing UEFI spec says that firmware should automatically add EFI_DISK_IO_PROTOCOL for all produced EFI_BLOCK_IO_PROTOCOL interfaces. Unfortunately U-Boot doesn't do this, so fallback to block I/O if disk I/O is not there.
1.14	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.
1.13	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.
1.12	20-Jun-2021	jmcneill	Add support for the boot services watchdog and pet it on every block I/O access. For slow media (like ISO image redirection on Lenovo HR330A BMC) this is needed because otherwise the default watchdog timeout fires before we can finish loading the kernel from install media.
1.11	26-May-2021	mrg	add basic raidframe support to efiboot. if raid disklabel or gpt is found, add this partition with the offset/size adjusted by RF_PROTECTED_SECTORS. note don't le32toh() the disklabel. if it was wrong-endian, then getdisklabel() will have swapped it. ok jmcneill thorpej.
1.10	28-Nov-2020	jmcneill	branches: 1.10.4; 1.10.6; Deal with devices that report either 512 or 2048 as logical block size for CD9660 file-systems.
1.9	18-Oct-2020	tnn	branches: 1.9.2; efiboot: recognize the EFI system partition as fstype MSDOS
1.8	11-Oct-2020	jmcneill	Add ISO9660 support.
1.7	27-Sep-2019	jakllsch	Use roundup2() instead of open coding something almost the same that truncates 64-bit quantities. Fixes disk access and booting in bootaa64.efi on SoftIron OverDrive 1000 (which does not have any memory below 4GiB).
1.6	21-Sep-2019	jmcneill	Honour block device's IO alignment requirements. Patch from Simon South <simon@simonsouth.net> in PR# 54554
1.5	09-Mar-2019	jmcneill	branches: 1.5.4; 1.5.6; Workaround a bug with ROCKPro64's U-Boot EFI implementation. The booted device path when booting from SD card sometimes does not include a MEDIA_DEVICE_PATH component, so in this case fallback to doing an exact match on the booted device path with the block device path to detect the default boot device.
1.4	01-Nov-2018	jmcneill	Add GPT support.
1.3	14-Sep-2018	jakllsch	MI efiboot: avoid LBA overflow in efi_block_find_partitions_disklabel()
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.
