* fdtdec: optionally add property no-map to created reserved memory nodeEtienne Carriere2020-09-221-2/+3
| | | | | | | | | | | | | | | | | | 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.

* lib: fdt: Introduce fdtdec_setup_mem_size_base_lowest()Michal Simek2020-08-201-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | 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>

Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style.

| | | | | | | | | | | | | | | | | | | | | | | | | | When using 32-bit addresses dtoc works correctly. For 64-bit addresses it does not since it ignores the #address-cells and #size-cells properties. Update the tool to use fdt64_t as the element type for reg properties when either the address or size is larger than one cell. Use the correct value so that C code can obtain the information from the device tree easily. Alos create a new type, fdt_val_t, which is defined to either fdt32_t or fdt64_t depending on the word size of the machine. This type corresponds to fdt_addr_t and fdt_size_t. Unfortunately we cannot just use those types since they are defined to phys_addr_t and phys_size_t which use 'unsigned long' in the 32-bit case, rather than 'unsigned int'. Add tests for the four combinations of address and size values (32/32, 64/64, 32/64, 64/32). Also update existing uses for rk3399 and rk3368 which now need to use the new fdt_val_t type.
