OF_HOSTFILE is used on sandbox configs only. Although it's pretty
unique and not causing any confusions, we are better of having simpler
config options for the DTB.
So let's replace that with the existing OF_BOARD. U-Boot would then
have only three config options for the DTB origin.
- OF_SEPARATE, build separately from U-Boot
- OF_BOARD, board specific way of providing the DTB
- OF_EMBED embedded in the u-boot binary(should not be used in production

xilinx: common: Enabling generic function for DT reselection2021-08-26T06:14:43+00:00Michal Simekmichal.simek@xilinx.com2021-08-11T12:23:54+00:00urn:sha1:52ff1626cf4c414c7a2423c443618017eb6e773c
U-Boot support board detection at run time and based on it change DT.
This feature is implemented for SOM Kria platforms which contain two
eeproms which contain information about SOM module and CC (Carrier card).
Full U-Boot starts with minimal DT file defined by
CONFIG_DEFAULT_DEVICE_TREE which is available in multi DTB fit image.
It is using default setup of board_name variable initializaed to
DEVICE_TREE which corresponds to CONFIG_DEFAULT_DEVICE_TREE option.
When DTB_RESELECT is enabled board_detection() is called. Keep it your mind
that this code is called before relocation. board_detection() is calling
xilinx_read_eeprom() which fills board_info (xilinx_board_description)
structure which are parsed in board_name_decode().
Based on DT configuration and amount of nvmemX aliases name of the board is
composed by concatenating CONFIG_SYS_BOARD "-" <board_name> "-rev"
<board_revision> "-" <cc_name> "-rev" <cc_revision>.
If CC is not present or more are available it keeps going.
When board name is composed and returned from board_name_decode() it is
assigned to board_name variable which is used by
board_fit_config_name_match() which is called via fdtdec_setup() when it
goes over config options in multi dtb FIT image.
From practical point of view multi DTB image is key point here which has to
contain configs for detected combinations. Unfortunately as of now they
have to be full DTBs and DTBOs are not supported.
That's why configuration like:
config_X {
description = "zynqmp-board-cc";
fdt = "board", "cc";
};
needs to be squashed together with:
fdtoverlay -o zynqmp-board-cc -i arch/arm/dts/zynqmp-board.dtb \
arch/arm/dts/zynqmp-cc.dtbo
and only one dtb is in fit:
config_X {
description = "zynqmp-board-cc";
fdt = "board-cc";
};
For creating multi DTBs fit image use mkimage -E, e.g.:
mkimage -E -f all.its all.dtb
When DTB_RESELECT is enabled xilinx_read_eeprom() is called before
relocation and it uses calloc for getting a buffer. Because this is dynamic
memory it is not relocated that's why xilinx_read_eeprom() is called again
as the part of board_init(). This second read with calloc buffer placed in
proper position board_late_init_xilinx() can setup u-boot variables as
before.

xilinx: Add support for generic board detection2021-08-26T06:14:43+00:00Michal Simekmichal.simek@xilinx.com2021-07-23T07:59:59+00:00urn:sha1:88232532728c91d69a1f5efb219f6cd7fc030461
Add support for changing DT at run time. It is done via board_detection()
which returns platform_id and platform_version which can be used via
board_name_decode() to compose board_local_name string which corresponds
with DT which is should be used.

Origin code was allocating only pointers to struct xilinx_board_description
and there was separate allocation for structure self and freeing in case of
failure.
The code is directly allocating space for all structures by one calloc to
simlify logic.

xilinx: Use variable for passing board_name2021-08-26T06:14:43+00:00Michal Simekmichal.simek@xilinx.com2021-07-23T07:55:59+00:00urn:sha1:57f710320fcd18bb5deaa9654dbce4da4de9d987
Use variable which points to DEVICE_TREE by default. The reason for this
change is to enable DTB_RESELECT and MULTI_DTB_FIT where board detection
can be used for change DTB at run time. That's why there must be reference
in board_fit_config_name_match() via variable instead of hardcoding it
which is sufficient for that use case.

xilinx: fru: Replace spaces with \0 in detected name2021-08-26T06:14:42+00:00Michal Simekmichal.simek@xilinx.com2021-08-12T09:03:49+00:00urn:sha1:530560b6f8eb06f89ee6d940701a24747bf12d2b
FRU spec expected \0 for unused symbols but unfortunately a lot of boards
are using spaces instead of \0. That's why after saving it to desc->name
name is checked again and all spaces are converted to \0. This will ensure
that names can be used for string manipulations like concatenation.

treewide: Convert macro and uses of __section(foo) to __section("foo")2021-05-24T18:21:30+00:00Marek Behúnmarek.behun@nic.cz2021-05-20T11:23:52+00:00urn:sha1:236f2ec43266cb4dabd320381498df6c9d80c82d
This commit does the same thing as Linux commit 33def8498fdd.
Use a more generic form for __section that requires quotes to avoid
complications with clang and gcc differences.
Remove the quote operator # from compiler_attributes.h __section macro.
Convert all unquoted __section(foo) uses to quoted __section("foo").
Also convert __attribute__((section("foo"))) uses to __section("foo")
even if the __attribute__ has multiple list entry forms.
