Subject: ar71xx: switch CPE/WBS 210/510 to okli-loader
|
|
|
|
We recently increased the kernel partition size of the CPE/WBS 210/510.
|
|
This works fine for new installations of the factory image, but on
|
|
sysupgrades, the partition table read by the bootloader is not adjusted.
|
|
This limits the maximum size of the kernel loaded by the bootloader to the
|
|
old partition size.
|
|
|
|
While adjusting the partition table would be a cleanest solution, such a
|
|
migration would have to happen before an upgrade to a new version with a
|
|
newer kernel. This is error-prone and would require a two-step upgrade, as
|
|
we mark the partition table partition read-only.
|
|
|
|
Instead, switch from the lzma-loader with embedded kernel to the
|
|
okli-loader, so only the tiny lzma-loader is loaded by the bootloader as
|
|
"kernel", and the lzma-loader will then load the rest of the kernel by
|
|
itself.
|
|
|
|
