fdtdec: correct test on return of fdt_node_offset_by_phandle

2020-10-06T15:07:54Z

The result of fdt_node_offset_by_phandle is negative for error, so this patch corrects the check of this result in fdtdec_parse_phandle_with_args. This patch allows to have the same behavior with or without OF_LIVE for the function dev_read_phandle_with_args with cell_name = NULL and with invalid phandle.

fdtdec: optionally add property no-map to created reserved memory node

2020-09-22T18:54:13Z

Add boolean input argument @no_map to helper function fdtdec_add_reserved_memory() to add or not "no-map" property for an added reserved memory node. Property no-map is used by the Linux kernel to not not map memory in its static memory mapping. It is needed for example for the| consistency of system non-cached memory and to prevent speculative accesses to some firewalled memory. No functional change. A later change will update to OPTEE library to add no-map property to OP-TEE reserved memory nodes. Signed-off-by: Etienne Carriere Signed-off-by: Patrice Chotard Reviewed-by: Simon Glass

lib: fdt: Fix fdtdec_setup_mem..() conversion to livetree API

2020-09-16T20:54:00Z

Repair incorrectly negated condition in the original patch which broke DT memory node parsing on everything which has more than one DT memory node, e.g. R-Car3. In case multiple valid memory nodes are present in the DT, the original patch would complete parsing cycle for the first memory node, then move on to the next one, identify it as a valid, and end the parsing. The fix is to invert the condition, to make the code behave as it did before the livetree conversion, so it would continue parsing the subsequent memory nodes as well.

CONFIG_NR_DRAM_BANKS: Remove unreferenced code as its always defined

2020-08-26T07:19:16Z

Since commit 86cf1c82850f ("configs: Migrate CONFIG_NR_DRAM_BANKS") & commit 999a772d9f24 ("Kconfig: Migrate CONFIG_NR_DRAM_BANKS"), CONFIG_NR_DRAM_BANKS is always defined with a value (4 is default). It makes no sense to still carry code that is guarded with "#ifndef CONFIG_NR_DRAM_BANKS" (and similar). This patch removes all these unreferenced code paths.

lib: fdt: Introduce fdtdec_setup_mem_size_base_lowest()

2020-08-20T07:49:20Z

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 Reviewed-by: Simon Glass
