2018-09-25dm: Update README.txt to clarify device tree usageTom Rini
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.

K3 specific SoCs have a dedicated microcontroller for doing resource management. Any HLOS/firmware on compute clusters should load a firmware to this microcontroller before accessing any resource. Adding support for loading this firmware. After the K3 system controller got loaded with firmware and started up it sends out a boot notification message through the secure proxy facility using the TI SCI protocol. Intercept and receive this message through the rproc start operation which will need to get invoked explicitly after the firmware got loaded.

2018-09-10arm: armv7-a: Compile and tune for armv7-a instead of armv5Adam Ford
arch/arm/Makefile references armv5 for backwards compatibility with older compilers. This patch removes those references to armv5, since by now newer compilers are required which should have armv7 support enabled. The Makefile also also has a list of options for mtune, but the entry for CONFIG_CPU_V7A is empty, so this patch tunes the CPU_V7A architecture to generic-armv7-a.

2018-08-20x86: coreboot: Add generic coreboot payload supportBin Meng
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.

2018-07-23doc: Replace DocBook with sphinx-based docsMario Six
The Linux kernel moved to sphinx-based documentation and got rid of the DocBook based documentation quite a while ago. Hence, the DocBook documentation for U-Boot should be converted as well. To achieve this, import the necessary files from Linux v4.17, and convert the current DocBook documentation (three files altogether) to sphinx/reStructuredText. For now, all old DocBook documentation was merged into a single handbook, tentatively named "U-Boot Hacker Manual". For some source files, the documentation style was changed to comply with kernel-doc; no functional changes were applied. Signed-off-by: Mario Six <mario.six@gdsys.cc>
