The Upstream Linux community has discontinued support for the target.
Maintaining support for it downstream would require too much effort.
Moreover, it seems that the supported hardware is no longer deemed worthy
of it.

-Subject: [PATCH] disk/part.c: use unsigned format when printing capacity
-To: u-boot@lists.denx.de
-
-Large disks otherwise produce highly unplausible output such as
- Capacity: 1907729.0 MB = 1863.0 GB (-387938128 x 512)
-
-As supposedly all size-related decimals are unsigned, use unsigned
-format in printf statement, resulting in a correct capacity being
-displayed:
- Capacity: 1907729.0 MB = 1863.0 GB (3907029168 x 512)

-Subject: [PATCH 67/69] generic: Mangle bootloader's kernel arguments
-
-The command-line arguments provided by the boot loader will be
-appended to a new device tree property: bootloader-args.
-If there is a property "append-rootblock" in DT under /chosen
-and a root= option in bootloaders command line it will be parsed
-and added to DT bootargs with the form: <append-rootblock>XX.
-Only command line ATAG will be processed, the rest of the ATAGs
-sent by bootloader will be ignored.
-This is usefull in dual boot systems, to get the current root partition
-without afecting the rest of the system.
