The Raspberry Pi Foundation released the new Zero 2 W which we
want to detect, so we can detect the correct device tree file name.

sandbox: Remove OF_HOSTFILE

2021-10-27T20:38:26+00:00

OF_HOSTFILE is used on sandbox configs only.  Although it's pretty
unique and not causing any confusions,  we are better of having simpler
config options for the DTB.

So let's replace that with the existing OF_BOARD.  U-Boot would then
have only three config options for the DTB origin.
- OF_SEPARATE, build separately from U-Boot
- OF_BOARD, board specific way of providing the DTB
- OF_EMBED embedded in the u-boot binary(should not be used in production

rpi: Conditionally add simple-framebuffer node

2021-09-15T11:34:06+00:00

It appears that RPi firmware has already added framebuffer
node under /chosen, at least on RPi 2 versions. So check
for this and don't add duplicate node.

arm: Disable ATAGs support

2021-09-07T20:22:30+00:00

With the exceptions of ds109, ds414, icnova-a20-swac, nokia_rx51 and
stemmy, disable ATAG support.  A large number of platforms had enabled
support but never supported a kernel so old as to require it.  Further,
some platforms are old enough to support both, but are well supported by
devicetree booting, and have been for a number of years.  This is
because some of the ATAGs related functions have been re-used to provide
the same kind of information, but for devicetree or just generally to
inform the user.  When needed still, rename these functions to
get_board_revision() instead, to avoid conflicts.  In other cases, these
functions were simply unused, so drop them.

rpi: Add identifier for the new CM4

2021-02-18T10:56:25+00:00

The Raspberry Pi Foundation released the new Compute Module 4 which we
want to detect, so we can enable Ethernet on it and know the correct
device tree file name.

Note that this sets the Ethernet option to true since the official CM4
IO board has an Ethernet port. But that might not be the case when using
custom ones.

rpi: limit size of the RAM to the multiple of the MMU_SECTION_SIZE

2021-02-18T10:56:25+00:00

When RPi4 is booted from USB Mass Storage, the firmware reports 947MiB of
the ARM memory (948 in case of the standard SD-card boot). This value is
not MMU_SECTION_SIZE aligned, so the dram_bank_mmu_setup() skips mapping
of the last 1MiB. This later causes u-boot in ARM 32bit mode to freeze,
because it relocated itself into that unmapped memory and fails to
execute.

Fix this by limiting the size of the first bank to the multiple of
MMU_SECTION_SIZE.

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
