2021-02-02common: Drop asm/global_data.h from common headerSimon Glass1-0/+1
Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

2021-01-05dm: Use access methods for dev/uclass private dataSimon Glass1-1/+1
Most drivers use these access methods but a few do not. Update them. In some cases the access is not permitted, so mark those with a FIXME tag for the maintainer to check.

Try to maintain some consistency between these variables by using _plat as a suffix for them. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-13dm: treewide: Rename 'platdata' variables to just 'plat'Simon Glass1-1/+1
We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-07-17treewide: convert bd_t to struct bd_info by coccinelleMasahiro Yamada1-1/+1
The Linux coding style guide (Documentation/process/coding-style.rst) clearly says: It's a **mistake** to use typedef for structures and pointers. Besides, using typedef for structures is annoying when you try to make headers self-contained. Let's say you have the following function declaration in a header: void foo(bd_t *bd); This is not self-contained since bd_t is not defined. To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h> #include <asm/u-boot.h> void foo(bd_t *bd); Then, the include direcective pulls in more bloat needlessly. If you use 'struct bd_info' instead, it is enough to put a forward declaration as follows: struct bd_info; void foo(struct bd_info *bd); Right, typedef'ing bd_t is a mistake. I used coccinelle to generate this commit. The semantic patch that makes this change is as follows: <smpl> @@ typedef bd_t; @@ -bd_t +struct bd_info </smpl> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2020-01-17common: Move hang() to the same header as panic()Simon Glass1-0/+1
At present panic() is in the vsprintf.h header file. That does not seem like an obvious choice for hang(), even though it relates to panic(). So let's put hang() in its own header.

2020-01-07ddr: socfpga: Enable ARM64 Non-Secure SDRAM ECC AccessThor Thayer1-3/+3
The ECC registers in the SDRAM HMC Adapter should always be accessible (both when ECC is enabled and disabled). Currently, the registers are accessible only when ECC is enabled. The ECC Enabled bit is used to determine the status of ECC by later OSes so always allow access.

2019-12-02common: Move some cache and MMU functions out of common.hSimon Glass1-0/+1
These functions belong in cpu_func.h. Another option would be cache.h but that code uses driver model and we have not moved these cache functions to use driver model. Since they are CPU-related it seems reasonable to put them here. Move them over. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>

Stratix 10 maps dram from 0 to 128GB. There is a 2GB hole in the memory for peripherals and other IO from 2GB to 4GB. However the dram controller ignores upper address bits for smaller dram configurations. Example: a 4GB dram maps to multiple locations, every 4GB on the address.
