spl: fit: Also record architecture in /fit-images

2021-06-23T07:48:36+00:00

On ARM64 secure OS can run as 64bit or 32bit that's why it is necessary to
record information about architecture that other code can read it and
properly pass it to TF-A and start in 64bit or 32bit mode.

Add the following functions to get a specific device's DMA ranges:
 - dev_get_dma_range()
 - ofnode_get_dma_range()
 - of_get_dma_range()
 - fdt_get_dma_range()
They are specially useful in oder to be able validate a physical address

treewide: convert bd_t to struct bd_info manually

Some code was not converted by coccinelle, somehow.

I manually fixed up the remaining, and comments, README docs.

treewide: convert bd_t to struct bd_info by coccinelle

2020-07-17T13:30:13+00:00

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 

  #include 
  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:

  
  @@
  typedef bd_t;
  @@
  -bd_t
  +struct bd_info

common: Move device-tree setup functions to fdt_support.h

2020-01-17T18:27:27+00:00

These functions relate to setting up the device tree for booting the OS.
The fdt_support.h header file supports similar functions, so move these
there.

fdt_support.h is missing declarations for bd_t. Including asm/u-boot.h
pulls in the definition.
