ARM: uniphier: enable distro boot
Switch to the distro boot for UniPhier platform. - Remove the environment vairalbes used to load images from raw block devices. - Keep the command to download images via tftp. This will be useful to boot the kernel when no valid kernel image is ready yet in the file system. - Use root.cpio.gz instead of root.cpio.uboot because we always know the file size of the init ramdisk; it is loaded via either a file system or network. - Rename fit_addr_r to kernel_addr_r, which the distro command checks to get the load address of FIT image.

Deployment for Distro Boot
|
||||
--------------------------
|
||||
|
||||
UniPhier SoC family boot the kernel in a generic manner as described in
|
||||
doc/README.distro .
|
||||
|
||||
To boot the kernel, you need to deploy necesssary components to a file
|
||||
system on one of your block devices (eMMC, NAND, USB drive, etc.).
|
||||
|
||||
The components depend on the kernel image format.
|
||||
|
||||
[1] Bare images
|
||||
|
||||
- kernel
|
||||
- init ramdisk
|
||||
- device tree blob
|
||||
- boot configuration file (extlinux.conf)
|
||||
|
||||
Here is an exmple of the configuration file.
|
||||
|
||||
-------------------->8--------------------
|
||||
menu title UniPhier Boot Options.
|
||||
|
||||
timeout 50
|
||||
default UniPhier
|
||||
|
||||
label UniPhier
|
||||
kernel ../Image
|
||||
initrd ../rootfs.cpio.gz
|
||||
fdtdir ..
|
||||
-------------------->8--------------------
|
||||
|
||||
Then, write 'Image', 'rootfs.cpio.gz', 'uniphier-ld20-ref.dtb' (DTB depends on
|
||||
your board), and 'extlinux/extlinux.conf' to the file system.
|
||||
|
||||
[2] FIT
|
||||
|
||||
- FIT blob
|
||||
- boot configuration file (extlinux.conf)
|
||||
|
||||
-------------------->8--------------------
|
||||
menu title UniPhier Boot Options.
|
||||
|
||||
timeout 50
|
||||
default UniPhier
|
||||
|
||||
label UniPhier
|
||||
kernel ../fitImage
|
||||
-------------------->8--------------------
|
||||
|
||||
Since the init ramdisk and DTB are contained in the FIT blob,
|
||||
you do not need to describe them in the configuration file.
|
||||
Write 'fitImage' and 'extlinux/extlinux.conf' to the file system.
