6c97a20d0b ppc/85xx: Introduce RESET_VECTOR_ADDRESS to handle non-standard link address
Some board ports place TEXT_BASE at a location that would cause the
RESET_VECTOR_ADDRESS not to be at 0xfffffffc when we link.  By default
we assume RESET_VECTOR_ADDRESS will be 0xfffffffc if the board doesn't
explicitly set it.

6ac9f47977 start a linker script helper file
Start a common header file for common linker script code (such as
workarounds for older linkers) rather than doing this in the build system.

As fallout, we no longer execute the linker every time config.mk is
included by a build file (which can easily be 70+ times), but rather only
execute it once.

This also fixes a bug in the major version checking by creating a macro to
easily compare versions and keep people from making the same common
mistake (forgetting to check major and minor together).

1aada9cd64 Fix all linker scripts for older binutils versions (pre-2.16)
Commit f62fb99941 fixed handling of all rodata sections by using a
wildcard combined with calls to ld's builtin functions SORT_BY_ALIGNMENT()
and SORT_BY_NAME().  Unfortunately these functions were only
introduced with biunutils version 2.16, so the modification broke
building with all tool chains using older binutils.

This patch makes it work again.  This is done by omitting the use of
these functions for such old tool chains.  This will result in
slightly larger target binaries, as the rodata sections are no longer
in optimal order alignment-wise which reauls in unused gaps, but the
effect was found to be insignificant - especially compared to the fact
that you cannot build U-Boot at all in the current state.

As ld seems to have no support for conditionals we run the linker
script through the C preprocessor which can be easily used to remove
the unwanted function calls.

Note that the C preprocessor must be run with the "-ansi" (or a
"-std=") option to make sure all the system-specific predefined
macros outside the reserved namespace are suppressed. Otherise, cpp
might for example substitute "powerpc" to "1", thus corrupting for
example "OUTPUT_ARCH(powerpc)" etc.

f772acf8a5 ARM: compiler options cleanup - improve tool chain support
For some time there have been repeated reports about build problems
with some ARM (cross) tool chains.  Especially issues about
(in)compatibility with the tool chain provided runtime support
library libgcc.a caused to add and support a private implementation
of such runtime support code in U-Boot.  A closer look at the code
indicated that some of these issues are actually home-made.  This
patch attempts to clean up some of the most obvious problems and make
building of U-Boot with different tool chains easier:

- Even though all ARM systems basicy used the same compiler options
  to select a specific ABI from the tool chain, the code for this was
  distributed over all cpu/*/config.mk files.  We move this one level
  up into lib_arm/config.mk instead.

- So far, we only checked if "-mapcs-32" was supported by the tool
  chain; if yes, this was used, if not, "-mabi=apcs-gnu" was
  selected, no matter if the tool chain actually understood this
  option.  There was no support for EABI conformant tool chains.
  This patch implements the following logic:

  1) If the tool chain supports
	"-mabi=aapcs-linux -mno-thumb-interwork"
     we use these options (EABI conformant tool chain).
  2) Otherwise, we check first if
	"-mapcs-32"
     is supported, and then check for
	"-mabi=apcs-gnu"
     If one test succeeds, we use the first found option.
  3) In case 2), we also test if "-mno-thumb-interwork", and use
     this if the test succeeds. [For "-mabi=aapcs-linux" we set
     "-mno-thumb-interwork" mandatorily.]

  This way we use a similar logic for the compile options as the
  Linux kernel does.

- Some EABI conformant tool chains cause external references to
  utility functions like raise(); such functions are provided in the
  new file lib_arm/eabi_compat.c

  Note that lib_arm/config.mk gets parsed several times, so we must
  make sure to add eabi_compat.o only once to the linker list.

12e9043c7e config.mk: Remove $(PCI_CLOCK) reference
The following commit introduced $(PCI_CLOCK) reference so that
we could tweak `PCI_66M' definition via an environment variable.

> Date:   Thu Jul 28 10:08:46 2005 -0500
>
>     * Patch by Eran Liberty
>       Add support for the Freescale MPC8349ADS board.

But I suggest a removal of it for the following reasons:

* In 2006, MPC8349ADS was merged into MPC8349EMDS port,
  and it seems that MPC8349EMDS port is PCI_66M free.

* OTOH, PCI_66M is used by MPC832XEMDS an MPC8360EMDS ports,
  but they don't need $(PCI_CLOCK) environment variable at all.
  PCI_66M is automatically configured via $(BOARD)_config names
  with the help of $(findstring _66_,$@).

* Unfortunately $(PCI_CLOCK) has been undocumented anywhere,
  so only a few people know the existence of it these days.

* Keep config.mk independent from $(BOARD) as much as possible.

31f30c9eb6 add %.c->%.i and %.c->%.s rules
The Linux kernel has some helper rules which allow you to quickly produce
some of the intermediary files from C source.  Specifically, you can
create .i files which is the preprocessed output and you can create .s
files which is the assembler output.  This is useful when you are trying
to track down header/macro expansion errors or inline assembly errors.

5ec5529b82 allow boards to customize compiler options on a per-file/dir basis
With our Blackfin boards, we like to build the compression routines with
-O2 as our tests show a pretty good size/speed tradeoff.  For the rest of
U-Boot though, we want to stick with the default -Os as that is mostly
control code.  So in our case, we would add a line like so to the board
specific config.mk file:
	CFLAGS_lib_generic += -O2

Now all files under lib_generic/ will have -O2 appended to their build.

28eab0d773 Conditionally add -fno-stack-protector to CFLAGS
When compile-testing on powerpc, I get errors like this:

net/nfs.c:422: undefined reference to `__stack_chk_fail_local'

This seems to be because -fstack-protector is on by default, so
let's explicitly disable it on all architectures that support the
option.

The Ubuntu toolchain is affected by this problem, and according to
Mike Frysinger, Gentoo has been running with SSP enabled for years.
More and more distros are turning SSP on by default, so this problem
is likely to get worse in the future.

Also, powerpc just happens to be one of the arches I do
compile-testing on. There may be other arches affected by this too.

Use cpp and sed to postprocess config.h and import the defined values
into include/autoconf.mk.  autoconf.mk is then included by config.mk to

Doing this enables conditional compilation at the Makefile level instead
of by wrapping every .c file with #ifdef/#endif wrappers.

e11887a77d Don't pass any debug options directly to the assembler
When passing the -g option to gcc, gcc automatically selects a

f93286397e Add support for a saving build objects in a separate directory.
Modifications are based on the linux kernel approach and
support two use cases:

  1) Add O= to the make command line
  'make O=/tmp/build all'

  2) Set environement variable BUILD_DIR to point to the desired location
  'export BUILD_DIR=/tmp/build'
  'make'

The second approach can also be used with a MAKEALL script
'export BUILD_DIR=/tmp/build'
'./MAKEALL'

Command line 'O=' setting overrides BUILD_DIR environent variable.

When none of the above methods is used the local build is performed and
the object files are placed in the source directory.

- add DTT support for adm1021 (new file dtt/adm1021.c; config

  (requires CONFIG_DTT_ADM1021, CONFIG_DTT_SENSORS, and

  behaves in a similar way to "eeprom_read()" etc.
- add 8260 FCC ethernet loopback code (new "eth_loopback_test()"
  function which is enabled by defining CONFIG_ETHER_LOOPBACK_TEST)
- gdbtools copyright update
- ensure that set_msr() executes the "sync" and "isync" instructions
  after the "mtmsr" instruction in cpu/mpc8260/interrupts.c
- 8260 I/O ports fix: Open Drain should be set last when configuring
- add SIU IRQ defines for 8260
- allow LDSCRIPT override and OBJCFLAGS initialization: change to
  config.mk to allow board configurations to override the GNU
  linker script, selected via the LDSCRIPT, make variable, and to
  give an initial value to the OBJCFLAGS make variable
- 8260 i2c enhancement:
  o correctly extends the timeout depending on the size of all
    queued messages for both transmit and receive
  o will not continue with receive if transmit times out
  o ensures that the error callback is done for all queued tx
    and rx messages
  o correctly detects both tx and rx timeouts, only delivers one to
    the callback, and does not overwrite an earlier error
  o logic in i2c_probe now correct
- add "vprintf()" function so that "panic()" function can be
  technically correct
- many Hymod board changes
