2022-01-25dm: Fix OF_BAD_ADDR definitionPatrice Chotard
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.

2021-12-23fdt: Don't call board_fdt_blob_setup() without OF_BOARDSimon Glass
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. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-08-20lib: fdt: Introduce fdtdec_setup_mem_size_base_lowest()Michal Simek
New function should be called from board dram_init() because it initialized gd->ram_base/ram_size. It finds the lowest available memory. On systems with multiple memory nodes finding out the first memory node by fdtdec_setup_mem_size_base() is not enough because this memory can be above actual U-Boot VA mapping. Currently only mapping till 39bit is supported (Full 44bit mapping was removed by commit 7985cdf74b28 ("arm64: Remove non-full-va map code")). If DT starts with the first memory node above 39bit address then system can be unpredictable. The function is available only when multiple memory bank support is enabled. Calling fdtdec_setup_memory_banksize() from dram_init() is not possible because fdtdec_setup_memory_banksize() is saving dram information to bd structure which is placed on stack but not initialized at this time. Also stack is placed at location setup in dram_init(). Signed-off-by: Michal Simek <michal.simek@xilinx.com> Reviewed-by: Simon Glass <sjg@chromium.org>

The phandlep pointer returning the phandle to the caller is optional and if it is not set when calling fdtdec_add_reserved_memory() it is highly likely that the caller is not interested in a phandle to the created reserved-memory area and really just wants that area added.

2019-11-14fdtdec: protect against another NULL phandlep in fdtdec_add_reserved_memory()Heiko Stuebner
The change adding fdtdec_add_reserved_memory() already protected the added phandle against the phandlep being NULL - making the phandlep var optional. But in the early code checking for an already existing carveout this check was not done and thus the phandle assignment could run into trouble, so add a check there as well, which makes the function still return successfully if a matching region is found, even though no-one wants to work with the phandle.
