Subject: main/u-boot-rockchip: Add board, which requires TPL blob
To: ~alpine/devel@lists.alpinelinux.org
Content-Type: text/plain; charset="UTF-8"

Hi,

I would like to add support for the Radxa Zero 3E [1] to main/u-boot-rockchip.

U-Boot requires an additional TPL (third program loader) for this
board. The TPL (and more) can be found at [2], which I would like to
package first. For boards requiring such a TPL, one has to set the
ROCKCHIP_TPL variable referencing the TPL when building U-Boot. Due to
this I would call the package "rockchip-tpl".

Anyone could tell me, if that [3] is an MIT license?

I tried arch="aarch64" before, as U-Boot requires the TPL to boot
aarch64. Imho, they don't make much sense on i. e. "x86-64" other than
cross-building U-Boot.
Though, they're identified as "data" only and abuild said, that
"noarch" would be better. Should I stick to "noarch"?

Below you can find the APKBUILD I've screwed up so far. (Copy'n'paste just
replaced the tabs.)

Cheers,
    Daniel Martin
