Try and package mainline u-boot with Pali's fixes for N900 #411

This can probably fit in arm-sdk's N900 build script in a similar fashion to how Pinephone's u-boot is built.

parazyd commented 4 years ago

So I've added support for this in https://github.com/parazyd/arm-sdk/commit/a5ad681c5417f962c947210885cf483f0bc9628b and propagated the change to image-builder in https://github.com/maemo-leste/image-builder/commit/e2665e3520ecfb963ab572ad0e34295726f125b4

Let's see if we can use 0xFFFF to flash this, and note it down on the wiki.

hmm, do we need u-boot.img or u-boot.bin ?

parazyd@rishi:~/src/u-boot$ file u-boot.bin
u-boot.bin: COM executable for DOS

parazyd@rishi:~/src/u-boot$ file u-boot.img
u-boot.img: u-boot legacy uImage, U-Boot 2020.07-rc5-00096-g04da1c\270, Firmware/ARM, Firmware Image (Not compressed), 250320 bytes, Sun Jul  5 23:11:09 2020, Load Address: 0x80008000, Entry Point: 0x80008000, Header CRC: 0xE258FAFA, Data CRC: 0x0DB2635B

I have done this, and it's at https://maedevu.maemo.org/images/n900/tools/

Do we update the wiki to have people use this version now? I'd say that could make sense. We can also wait for the patches to land, but eh.

parazyd commented 3 years ago

If at all possible, I would like to also have it packaged like this: https://github.com/maemo-leste/pine64-uboot

This way we can keep it up to date on the device if necessary. For this I'd prefer if the patches are in u-boot's git master.

wrt. wiki and generally booting (for the first time) - yes, we'll need a binary available like that so we can add it to the wiki ASAP.

Ok, so this ticket is now about creating a package for it, then?

14:58 < Wizzup> Pali: do you create your bootmenu entries from fremantle still, or do you manage them
                externally? I'm wondering what the best way for leste to manage this would be
14:58 < Wizzup> I think we probably want some bootmenu.scr file on the sd card
14:58 < Wizzup> I was looking at u-boot/include/configs/nokia_rx51.h but it wasn't quite clear to me
14:59 < Wizzup> reading u-boot doc...
15:01 < Pali> IIRC upstream u-boot read bootmenu.scr also from sd card
15:01 < Wizzup> any clue what has preference?
15:01 < Wizzup> or are they combined somehow?
15:01 < Wizzup> I saw the preboot section
15:02 < Pali> now I checked it
15:02 < Pali> yes, it first loads it from sd card and then fallbacks to emmc
15:02 < Pali> include/configs/nokia_rx51.h
15:02 < Pali> preboot=
15:02 < Wizzup> ok, so if we have it on sd card we better make sure we have fremantle entry to allow
                booting fremantle with sd card in
15:02 < Pali> yes!
