libfdt: Introduce new ARCH_FIXUP_FDT option

2016-08-01T01:37:08+00:00

Add new Kconfig option to disable arch_fixup_fdt() calls for cases where
U-Boot shouldn't update memory setup in DTB file.
One example of usage of this option is to boot OS with different memory
setup than U-Boot use.

efi_loader: Call fdt preparation functions

2016-03-16T01:30:14+00:00

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.

Kconfig: Move CONFIG_FIT and related options to Kconfig

2016-03-14T23:18:07+00:00

There are already two FIT options in Kconfig but the CONFIG options are
still in the header files. We need to do a proper move to fix this.

Move these options to Kconfig and tidy up board configuration:

   CONFIG_FIT
   CONFIG_OF_BOARD_SETUP
   CONFIG_OF_SYSTEM_SETUP
   CONFIG_FIT_SIGNATURE
   CONFIG_FIT_BEST_MATCH
   CONFIG_FIT_VERBOSE
   CONFIG_OF_STDOUT_VIA_ALIAS
   CONFIG_RSA

Unfortunately the first one is a little complicated. We need to make sure
this option is not enabled in SPL by this change. Also this option is
enabled automatically in the host builds by defining CONFIG_FIT in the
image.h file. To solve this, add a new IMAGE_USE_FIT #define which can
be used in files that are built on the host but must also build for U-Boot
and SPL.

Note: Masahiro's moveconfig.py script is amazing.

common: image-fdt: correct fdt_blob for IMAGE_FORMAT_LEGACY

2015-12-05T23:22:15+00:00

If condition of "(load == image_start || load == image_data)" is true,
should use "fdt_addr = load;", but not "fdt_blob = (char *)image_data;",
or fdt_blob will be overridden by "fdt_blob = map_sysmem(fdt_addr, 0);"
at the end of the switch case.

fdt: Pass the device serial number through devicetree

2015-06-05T14:32:07+00:00

Before device-tree, the device serial number used to be passed to the kernel
using ATAGs (on ARM). This is now deprecated and all the handover to the kernel
should now be done using device-tree. Thus, this passes the serial-number
property to the kernel using the serial-number property of the root node, as
expected by the kernel.

The serial number is a string that somewhat represents the device's serial
number. It might come from some form of storage (e.g. an eeprom) and be
programmed at factory-time by the manufacturer or come from identification
bits available in e.g. the SoC.

common: Make sure arch-specific map_sysmem() is defined

2015-04-18T17:11:09+00:00

In the case where the arch defines a custom map_sysmem(), make sure that
including just mapmem.h is sufficient to have these functions as they
are when the arch does not override it.

Also split the non-arch specific functions out of common.h

fdt: Allow non-FDT kernels to boot when CONFIG_OF_LIBFDT is defined

2014-12-08T14:35:47+00:00

The boot commands - bootz/bootm mandate a third argument which is the
address to the FDT blob. In cases where this argument is not specified,
boot fails with a message indicating a missing FDT.

This causes non-FDT kernels to fail to boot. This patch allows both FDT
and non-FDT kernels to boot by making the third parameter to the bootm/bootz
optional.
