* Documentation: boards: stm32mp: document eMMC boot configurationAhmad Fatoum2020-09-141-1/+12
| | | | | | | | | | In order to boot from eMMC on the STM32MP15x, the boot_ack bit in the ext_csd register must be set. Document this and while at it, fix a misformatted code block in the same section.

| * ARM: stm32mp: add support for Seeed Odyssey boardAhmad Fatoum2020-08-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Board consists of SoM with stm32mp157c with 4G eMMC and 512M DDR3 RAM. Carrier board features USB and ETH interfaces and SD card connector. USB and ETH interfaces not yet operational. Boot from eMMC requires boot ack bit set. Device Tree taken from v5 of kernel device tree off mailing list[1].

| |/ | | | | | | | | | | | | | | | | This renames the dcdofs config option in the imx-image tool to ivtofs. dcdofs is a misnomer. The DCD (Device Configuration Data) is only one part of the data linked into the IVT (Image Vector Table), but the meaning of the option is really the latter, not the former.

* / Documentation: devicetree: codify extension of upstream DTS by phandlesAhmad Fatoum2020-06-231-0/+43
|/ | | | | | | | | | | | | | | | Sync with the upstream device tree repository has been a common cause for breakage in barebox. Often unnoticed: * New bindings are merged upstream and device trees migrated, but barebox didn't yet have support * Nodes are renamed upstream, but barebox still extends the old name, with duplicate nodes resulting We can solve the second one by requiring dtc to give us errors when paths we extend no longer exist.

We also have gained one new board and some other new drivers since the last time the defconfig was touched, so enable them all, as well as some possibly useful commands.
