The larger switches of the Linksys LGS series (e.g. LGS352C) make
use of NAND. So the vendor firmware uses other commands to upload
an image through the WebUI.
Add the required scripts. With this we can upload an image to all
devices of that series. Independant of NOR or NAND.

Hardware specification
----------------------
* RTL8380M SoC, 1 MIPS 4KEc core @ 500MHz
* 256MB DRAM
* 32MB NOR Flash
* 8 x 10/100/1000BASE-T ports
* 2 x SFP ports
* Power LED, Fault LED
* Reset button on front panel
* UART (115200 8N1) via populated standard pin header marked JP1
TODO: The SFP ports use a shared SCL GPIO that the driver cannot handle.
The left SFP port (lan9) is defined and fully functional while the laser
on the right SFP port (lan10) is off by default.

Installation using OEM webinterface
-----------------------------------
1. Make sure you are running OEM firmware in secondary slot
2. Install squashfs-factory.imag to primary slot by upload via http
Installation using serial interface
-----------------------------------
1. Press "a" "c" "p" during message "Enter correct key to stop autoboot"
2. Load image with "upgrade runtime <TFTP IP>:squashfs-sysupgrade.bin" command
3. Switch to primary slot with "setsys bootpartition 0"
4. Store config with "savesys"
5. Boot the image with `boota` command
Dual-boot with stock firmware using writable u-boot-env
-------------------------------------------------------
From stock to OpenWrt / primary image 1 (CLI as admin):
- > boot system image1
- > reboot
From OpenWrt to stock / boot image 2: (shell as root)
- # fw_setsys bootpartition 1
- # reboot
Debrick using serial interface
------------------------------
1. Press "a" "c" "p" during message "Enter correct key to stop autoboot"
2. Load vendor image with "upgrade runtime <TFTP IP>:LGS310xxxxx.imag"
3. switch to primary partition "setsys bootpartition 0"
4. safe config "savesys"

[Add missing 'w' in name of firmware partition]
Signed-off-by: Sander Vanheule <sander@svanheule.net>
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)

The redundant character '0x0a' after the 192 bytes '0x00' padding broke
the factory image. We need to remove it to make things work again.

This commit adds the 'Build/linksys-image' rule and the
'linksys-image.sh' script to the build system.
This change is needed for generating factory images for the Linksys
EA6350v3 device. Without this patch, only valid sysupgrade images can be
generated. With this patch, users can flash the device without the
need of physical access or disassembly.
