* dm: Update README.txt to clarify device tree usageTom Rini2018-09-251-0/+9
| | | | | | | | | | | | | | In the section about Device Trees add a paragraph at the end that clarifies how we decide of a tree is valid or not. We say that all bindings must either be in the specification (link provided) or in our device-tree-bindings directory. We say that most of these come from the Linux Kernel and as such some design decisions are made for us already, but that in most cases we wish to retain compatibility.

This patch removes those references to armv5, since by now newer compilers are required which should have armv7 support enabled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently building U-Boot as the coreboot payload requires user to change the build configuration for a specific board during menuconfig process. This uses the board's native device tree to configure the hardware. For example, the device tree provides PCI address range for the PCI host controller and U-Boot will re-program all PCI devices' BAR to be within this range. In order to make sure we don't mess up the hardware, we should guarantee the range matches what coreboot programs the chipset. But we really should make the coreboot payload support easier. Just like EFI payload, we can create a generic coreboot payload for all x86 boards as well. The payload is configured to include as many generic drivers as possible. All stuff that touches low level initialization are not allowed as such is the coreboot's responsibility. Platform specific drivers (like gpio, spi, etc) are not included.

* x86: doc: Fix reference to EFI doc in U-BootBin Meng2018-06-171-7/+7
| | | | | | | | | | | Since commit f3b5056c4e72 ("efi_loader: split README.efi into two separate documents"), the original README.efi was renamed to README.u-boot_on_efi, but x86 doc still refers to the old one. This updates the x86 doc to reference both README.u-boot_on_efi and README.uefi. Signed-off-by: Bin Meng <bmeng.cn@gmail.com>
