Current factory image sizes for Linksys devices are 256-byte aligned. This
is not an issue writing factory images from the OpenWrt or Linksys GUIs,
but can lead to failures using a TFTP client from the Linksys bootloader:
NAND write: device 1 offset 0x2800000, size 0xc00100
Attempt to write to non page aligned data
NAND write to offset 2800000 failed -22
0 bytes written: ERROR
Simplify Linksys footer creation by migrating to a makefile build recipe,
and pre-pad the footer (with 0xFF) to ensure the final image is $(PAGESIZE)
aligned. Finally, remove the old linksys-image.sh script no longer needed.
Linksys footer details are given below for future reference. The 256-byte
footer is appended to factory images and tested by both the Linksys
Upgrader (observed in EA6350v3) and OpenWrt sysupgrade.
Footer format:
.LINKSYS. Checked by Linksys upgrader before continuing. (9 bytes)
<VERSION> Upgrade version number, unchecked so arbitrary. (8 bytes)
<TYPE> Model of device, space padded (0x20). (15 bytes)
<CRC> CRC checksum of factory image to flash. (8 bytes)
<padding> Padding ('0' + 0x20 * 7) (8 bytes)
<signature> Signature of signer, unchecked so arbitrary. (16 bytes)
<padding> Padding with nulls (0x00) (192 bytes)
