image: don't exceed gd->ram_top in bootm_size

2020-08-27T15:26:58+00:00

When board_get_usable_ram_top() limits gd->ram_top, env_get_bootm_size()
must not exceed that limit. Otherwise, boot_relocate_fdt() might put fdt
out of the allowed RAM range.

The similar commit 8ce1f10cf2b1 ("ARM: bootm: take into account
gd->ram_top") exposed this bug.

This fixes boot on Armada 8040 based Clearfog GT-8K where ram_top is set
to 0x80000000 (2GB), but bi_dram[0].size might be up to 0xc0000000
(3GB). Note the relocated fdt address (0xbfff4000) in the console output
listed below:

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

command: Remove the cmd_tbl_t typedef

2020-05-18T22:36:55+00:00

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.

Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.

This requires quite a few header-file additions.

common: Drop net.h from common header

2020-05-18T21:33:31+00:00

Move this header out of the common header. Network support is used in
quite a few places but it still does not warrant blanket inclusion.

Note that this net.h header itself has quite a lot in it. It could be
split into the driver-mode support, functions, structures, checksumming,
etc.

image: Add a common compression type detection function.

2020-04-17T16:32:36+00:00

Currently, there is no method that can detect compression types
given a file. This is very useful where a compressed kernel image
is loaded directly to the memory.

Inspect initial few bytes to figure out compression type of the
image. It will be used in booti method for now but can be reused
any other function in future as well.

dm: core: Create a new header file for 'compat' features

2020-02-06T02:33:46+00:00

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.

Move the compatibility features into a separate header file.
