ARM: Tegra210: Add support to common Tegra source/config files

2015-07-28T17:30:20+00:00

Derived from Tegra124, modified as appropriate during T210
board bringup. Cleaned up debug statements to conserve
string space, too. This also adds misc 64-bit changes
from Thierry Reding/Stephen Warren.

linux_compat: handle __GFP_ZERO in kmalloc()

2015-07-22T13:30:44+00:00

Currently, kzalloc() returns zero-filled memory, while kmalloc()
simply ignores the second argument and never fills the memory
area with zeros.

I want kmalloc(size, __GFP_ZERO) to behave as kzalloc() does,
which will make it easier to add more memory allocator variants.

With the introduction of __GFP_ZERO flag, going forward, kzmalloc()
variants can fall back to kmalloc() enabling the __GFP_ZERO flag.

linux_compat: move vzalloc() to header file as an inline function

2015-07-22T13:30:39+00:00

The vzalloc(size) is equivalent to kzalloc(size, 0).  Move it to
include/linux/compat.h as an inline function in order to avoid the
function call overhead.

fdt: Provide debug info when a device tree cannot be found

2015-07-21T23:39:28+00:00

It can be quite confusing with a new platform to figure out why the device
tree cannot be located. Add some debug information for this case.

lib: Add function to extract a number from the end of a string

2015-07-21T23:39:28+00:00

Split out the code in fdtdec which finds a number at the end of a string. It
can be useful in other situations.

Add rivest cipher 4 (rc4) implementation

2015-07-21T23:39:28+00:00

Add an implementation of RC4. This will be used by Rockchip booting but may
be useful in other situations.

Drop CONFIG_ERRNO_STR from SPL

2015-07-21T23:39:27+00:00

This bloats the code size quite a bit and is less useful in SPL where there
is no command line.

Avoid including this code in SPL.

fdt: Add fdt_first/next_region() functions

2015-07-21T23:39:20+00:00

These have been sent upstream but not accepted to libfdt. For now, bring
these into U-Boot to enable fdtgrep to operate. We will use fdtgrep to
cut device tree files down for SPL.

fdt: Add a function to remove unused strings from a device tree

2015-07-21T23:39:20+00:00

Property names are stored in a string table. When a node property is
removed, the string table is not updated since other nodes may have a
property with the same name.

Thus it is possible for the string table to build up a number of unused
strings. Add a function to remove these. This works by building a new device
tree from the old one, adding strings one by one as needed.
