fdt: Allow the devicetree to come from a bloblist

2024-01-07T20:45:07+00:00

Standard passage provides for a bloblist to be passed from one firmware
phase to the next. That can be used to pass the devicetree along as well.
Add an option to support this.

Tests for this will be added as part of the Universal Payload work.

include: fdtdec: decouple fdt_addr_t and phys_addr_t size

2023-05-06T09:28:18+00:00

The DT specification supports CPUs with both 32-bit and 64-bit addressing
capabilities. In U-boot the fdt_addr_t and phys_addr_t size are coupled
by a typedef. The MTD NAND drivers for 32-bit CPU's can describe partitions
with a 64-bit reg property. These partitions synced from Linux end up with
the wrong offset and sizes when only the lower 32-bit is passed.
Decouple the fdt_addr_t and phys_addr_t size as they don't necessary
match.

mtd: nand: sunxi: Convert from fdtdec to ofnode

2023-04-28T00:06:57+00:00

As a first step toward converting this driver to the driver model, use
the ofnode abstraction to replace direct references to the FDT blob.

Using ofnode_read_u32_index removes an extra pair of loops and makes the
allwinner,rb property optional, matching the devicetree binding.

dm: Fix OF_BAD_ADDR definition

2022-01-25T19:36:10+00:00

When OF_LIVE flag is enabled on a 64 bits platform, there is an
issue when dev_read_addr() is called and need to perform an address
translation using __of_translate_address().

In case of error, __of_translate_address() return's value is OF_BAD_ADDR
(wich is defined in include/dm/of.h to ((u64)-1) = 0xffffffffffffffff).
The return value of dev_read_addr() is often compared to FDT_ADDR_T_NONE
which is defined as (-1U) = 0xffffffff.
In this case the comparison is always false.

To fix this issue, define FDT_ADDR_T_NONE to (ulong)(-1) in case of
AARCH64. Update accordingly related tests.

fdt: Don't call board_fdt_blob_setup() without OF_BOARD

2021-12-23T15:24:40+00:00

At present this override function is called even when OF_BOARD is not
enabled. This makes it impossible to disable this feature and in fact
makes the OF_BOARD option useless.

Reinstate its intended purpose, so that it is possible to switch between
the appended devicetree and one provided by the board's custom function.

A follower patch adds warnings for this scenario, but for now we don't
have a Kconfig that definitively tells us that OF_BOARD should be used.
