Sorry for the supersede, this fixes a small issue with beaglebone where grub2 would overwrite the initrd while patching the device tree because it's missing boundary checks. - EFI: Map fdt as reserved * efi-map-fdt-as-reserved.patch - Fix OMAP3 boards to load u-boot from raw sector offset * omap3-Use-raw-SPL-by-default-for-mmc1.patch - Allow grub2 to find its config * efi_loader-Pass-proper-device-path-in-on-boot.patch - Fix Raspberry Pi 1 build * efi_loader-Provide-icache-flush-stub.patch - Move omap3 to distro bootcmd (to enable efi boot on beagle-xm) * omap3-Move-to-distro-bootcmd.patch - Add EFI patch to support FDT fixups (patches in RAM size) * efi_loader-Call-fdt-preparation-functions.patch - Patch the default u-boot env to search for dtb in /boot at part 2 * efi-default-env.patch - Use $fdtfile rather than $fdt_name everywhere: * efi2.patch - Add EFI support about to move upstream: * efi.patch - EFI: Map fdt as reserved * efi-map-fdt-as-reserved.patch - Fix OMAP3 boards to load u-boot from raw sector offset * omap3-Use-raw-SPL-by-default-for-mmc1.patch (forwarded request 365802 from algraf) OBS-URL: https://build.opensuse.org/request/show/366093 OBS-URL: https://build.opensuse.org/package/show/openSUSE:Factory/u-boot?expand=0&rev=68

Subject: [PATCH 1/1] efi_loader: Call fdt preparation functions
|
|
|
|
We have a nice framework around image fils to prepare a device tree
|
|
for OS execution. That one patches in missing device tree nodes and
|
|
fixes up the memory range bits.
|
|
|
|
We need to call that one from the EFI boot path too to get all those
|
|
nice fixups. This patch adds the call.
