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.

doc: replace @return by Return:

2022-01-19T17:11:34+00:00

Sphinx expects Return: and not @return to indicate a return value.

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.
