kbuild: rename SRCTREE to srctree

2014-03-12T21:04:57+00:00

Prior to Kbuild, $(TOPDIR) or $(SRCTREE) was used for
pointing to the top of source directory.
(No difference between the two.)

In Kbuild style, $(srctree) is used for instead.
This commit renames SRCTREE to srctree and deletes the
defition of SRCTREE.

Note that SRCTREE in scripts/kernel-doc, scripts/docproc.c,
doc/DocBook/Makefile should be keep.

fw_env: correct writes to devices with small erase blocks

2014-03-12T21:04:29+00:00

Some NOR flash devices have a small erase block size.  For example, the
Micron N25Q512 can erase in 4K blocks.  These devices expose a bug in
fw_env.c where flash_write_buf() incorrectly calculates bytes written
and attempts to write past the environment sectors.  Luckily, a range
check prevents any real damage, but this does cause fw_setenv to fail
with an error.

This change corrects the write length calculation.

The bug was introduced with commit 56086921 from 2008 and only affects
configurations where the erase block size is smaller than the total
environment data size.

fw_env: calculate default number of env sectors

2014-03-12T21:04:28+00:00

The assumed number of environment sectors (always 1) leads to an
incorrect top_of_range calculation in fw.env.c when a flash device has
an erase block size smaller than the environment data size (number of
environment sectors > 1).

This change updates the default number of environment sectors to at
least cover the size of the environment.

Also corrected a false statement about the number of sectors column in
fw_env.config.

tools/env: cross-compile fw_printenv without setting HOSTCC

2014-02-19T16:10:04+00:00

fw_printenv is a program which mostly runs on the target Linux.

Before switching to Kbuild, we needed to set HOSTCC at the
command line like this:
    make HOSTCC= env

Going forward we can cross compile it by specifying CROSS_COMPILE:
    make CROSS_COMPILE= env
This looks more natural.

tools: convert makefiles to kbuild style

2014-02-19T16:07:49+00:00

Before this commit, makefiles under tools/ directory
were implemented with their own way.

This commit refactors them by using "hostprogs-y" variable.

Several C sources have been added to wrap other C sources
to simplify Makefile.
For example, tools/crc32.c includes lib/crc32.c

Makefile: do not create a symbolic link to arch/${ARCH}/include/asm

2013-11-08T14:39:14+00:00

In-tree build:
  - Do not create a symbolic link
      from include/asm to arch/${ARCH}/include/asm
  - Add ${SRCTREE}/arch/arm/include into the header search path

Out-of-tree build:
  - Do not create a directory ${OBJTREE}/include2
  - Do not create a symbolic link
      from ${OBJTREE}/include2/asm to ${SRCTREE}/arch/${ARCH}/include/asm
  - Add ${SRCTREE}/arch/arm/include into the header search path
