we will move away from this numbering, the possibility seems remote at

Given that devices within a uclass will have an implied numbering, it
makes sense to build this into driver model as a core feature. The cost
is fairly small in terms of code and data space.

With each uclass having numbered devices we can ask for SPI port 0 or
serial port 1 and receive a single device.

Devices typically request a sequence number using aliases in the device
tree. These are resolved when the device is probed, to deal with conflicts.
Sequence numbers need not be sequential and holes are permitted.

stdio: Remove redundant code around stdio_register() calls

already been zeroed with memset().

Also, there is no need to create a stub function for stdio to call - if the

10 years agoAdd a simple malloc() implementation for pre-relocation
Simon Glass [Fri, 11 Jul 2014 04:23:28 +0000 (22:23 -0600)]
Add a simple malloc() implementation for pre-relocation

If we are to have driver model before relocation we need to support some
way of calling memory allocation routines.

The standard malloc() is pretty complicated:

1. It uses some BSS memory for its state, and BSS is not available before
relocation

2. It supports algorithms for reducing memory fragmentation and improving
performace of free(). Before relocation we could happily just not support
free().

3. It includes about 4KB of code (Thumb 2) and 1KB of data. However since
this has been loaded anyway this is not really a problem.

The simplest way to support pre-relocation malloc() is to reserve an area
of memory and allocate it in increasing blocks as needed. This
implementation does this.

To enable it, you need to define the size of the malloc() pool as described
in the README. It will be located above the pre-relocation stack on
supported architectures.

Note that this implementation is only useful on machines which have some
memory available before dram_init() is called - this includes those that
do no DRAM init (like tegra) and those that do it in SPL (quite a few
boards). Enabling driver model preior to relocation for the rest of the
boards is left for a later exercise.

Commit ddc94378d changed the definition of __kernel_size_t
from unsigned int to unsigned long.

It is true that it fixed warnings on some crosstools
but it increased warnings on the others.

The problem is that we cannot see consistency in terms of
the typedef of __kernel_size_t on M68K architecture.

However, I'd like to suggest to have __kernel_size_t to be
unsigned int again.

Rationale:

[1] Linux Kernel defines __kernel_size_t on M68K as unsigned int.
    Let's stick to the Linux's way.

[2] We want to build boards with popular pre-built toolchains,
    not the one locally-built by indivisuals.
    I think m68-linux-gcc which can be downloaded from www.kernel.org
    is the candidate for our _recommended_ toolchains.

With this patch, all the m68k boards can be built without any warnings.

Give it a try with the following crosstools:

https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.6.3/
x86_64-gcc-4.6.3-nolibc_m68k-linux.tar.xz

The last iteration does

scripts: add mailmapper, a tool to create/update mailmap file

This tool helps to create/update the mailmap file.

It runs 'git shortlog' internally and searches differently spelled author
names which share the same email address. The author name with the most
commits is asuumed to be a canonical real name. If the number of commits
from the cananonical name is equal to or greater than 'MIN_COMMITS' (=50),
the entry for the cananical name will be output. ('MIN_COMMITS' is used
here because we do not want to create a fat mailmap by adding every author
with only a few commits.)

If there exists a mailmap file specified by the mailmap.file configuration
options or '.mailmap' at the toplevel of the repository, it is used as
a base file.

The base file and the newly added entries are merged together and sorted
alphabetically (but the comment block is kept untouched), and then printed
to standard output.

 Usage
 -----

  scripts/mailmapper

prints the mailmapping to standard output.

  scripts/mailmapper > tmp; mv tmp .mailmap

will be useful for updating '.mailmap' file.

from text files, which means CRs ('\r') in front of LFs ('\n') are just ignored.

Drawback of enabling this option is that (maybe exported) variables which have
a trailing CR in their content will get imported without that CR. But this
