4Subject: [PATCH] Add extra sector count from section entry for EFI catalogue
5
6According to page 11: `Figure 5 - Section Entry' in El Torito Bootable
7CD-ROM Format Specification [1]. The sector count tooks 2 byte which
8means max sector count is 0xffff (65535), for 512-byte sector, the
9size of bootable image is no more than 32MB (65536 * 512 / 1024 / 1024)
10
11If the size of efi.img > 32MB, the partition table will be truncated
12in ISO, which caused UEFI system or grub-efi read efi.img broken
13occasionally.
14
15This patch extend efi_count, mac_count and count to 4 byte int, if
16Yocto defines `Selection criteria type = 2', add extra sector count
17to original sector count as total count; for other situation, still use
18original sector count as usual
19

1163- * fields are only for informational purposes for the administrator,
1164- * due to clock skew between nodes and hostname HA service takeover.
