* integrator: enable Vpp and disable flash protectionLinus Walleij2011-11-10-0/+20
| | | | | | | | | | This enables Vpp and disables the flash protection on the Integrator when starting U-Boot. The integrator/AP has double protection mechanisms: this one and the EBI protection bit (patch earlier), the Integrator/CP has only one line of protection in these registers.

* integrator: add system controller headerLinus Walleij2011-11-10-0/+91
| | | | | | | | Break out the AP system controller and CP "CP controller" registers into a header file, it gives better overview than hardcoding its values and other disturbing practices. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* integrator: make flash writeable on bootLinus Walleij2011-11-10-0/+77
| | | | | | | | | | | | | This reconfigures the EBI (External Bus Interface) on the integrator so that chip select 1, handling the flash memory, is set to writeable. Without this it is not possible for U-Boot to access flash memory and it crashes on startup since CFI won't work properly. Since this is the first time we use the EBI, we create a header file for its registers. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* integrator: use io-accessors for board initLinus Walleij2011-11-10-4/+5
| | | | | | | Casting around to *(volatile ulong *) doesn't look good, so include the <asm/io.h> macros and use good old readl() instead. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* integrator: move text offset to configLinus Walleij2011-11-10-5/+0
| | | | | | | Do away with the config.mk file and move the text offset to the config files to make things easier. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* integrator: do not test first part of the memoryLinus Walleij2011-11-08-4/+15
| | | | | | | | | | | When booting from Flash, the Integrator remaps its flash memory from 0x24000000 to 0x00000000, and starts executing it at 0x00000000. This ROM thus hides the RAM underneath and first 0x40000 bytes of the memory cannot be tested by get_ram_size(). So let's test from 0x40000 to the end of detected memory instead.

* punt unused clean/distclean targetsMike Frysinger2011-10-15-18/+0
| | | | | | | | | | The top level Makefile does not do any recursion into subdirs when cleaning, so these clean/distclean targets in random arch/board dirs never get used. Punt them all. MAKEALL didn't report any errors related to this that I could see. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* integrator: convert to new build systemLinus Walleij2011-09-03-220/+0
| | | | | | | | | | | | | | | | | This deletes the integrator split_by_variant.sh script and defines a number of unique board types for the core modules that are meaningful to support for the Integrator AP/CP, i.e. the ones that did not just say "unsupported core module" in split_by_variant.sh. If more core modules need to be supported they are easy to add. We delete all the old cruft in Makefile and MAKEALL that was working around the old way of building boards. We create a unique config file per board to satisfy the build system, but they are just oneliners that include the existing integratorap.h and integratorcp.h configs.

* integratorap: support relocationLinus Walleij2011-09-03-8/+7
| | | | | | | | | | The integrator board was apparently never converted over to support relocation until now. After this the integrator u-boot both compiles and boots on the Integrator AP. This also fixes the SDRAM memory size detection. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* integratorap: make the compile work againLinus Walleij2011-09-03-1/+1
| | | | | | | | | The integratorap/cp config for u-boot was outdated and would not even compile, so fix the obvious missing bits for it to start building. After this "make ap920t_config/make all" starts working again. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
* Rename TEXT_BASE into CONFIG_SYS_TEXT_BASEWolfgang Denk2010-10-18-2/+2
| | | | | | | | | | | | The change is currently needed to be able to remove the board configuration scripting from the top level Makefile and replace it by a simple, table driven script. Moving this configuration setting into the "CONFIG_*" name space is also desirable because it is needed if we ever should move forward to a Kconfig driven configuration system.

* board/armltd/integrator/split_by_variant.sh: fix 'echo -n'Andreas Bießmann2010-10-13-72/+57
| | | | | | | | | | | | | | This patch fixes an error when running MAKEALL for ARM9. On OS X /bin/sh uses builtin echo which does not utilise '-n' switch. GNU manual for builtins recomend to use here-document style to solve this portability issue. This patch removes the usage of 'echo -n' and replace by here-document style or a oneline echo command.

* ARMV7: Versatile Express Coretile CortexA9x4 supportMatt Waddel2010-10-13-0/+357
| | | | | | | | | | | | | | | Adds support for the ARM quad-core Cortex-A9 processor This system includes a motherboard(Versatile Express), daughterboard (Coretile), and SOC(Cortex-A9 quad core). The serial port, ethernet, and flash systems work with these additions. The naming convention is: SOC -> CortexA9 quad core = ca9x4 daughterboard -> Coretile = ct motherboard -> Versatile Express = vxp This gives ca9x4_ct_vxp.c as the board support file.

* Generic udelay() with watchdog supportIngo van Lil2009-12-05-1/+1
| | | | | | | | | | | | | According to the PPC reference implementation the udelay() function is responsible for resetting the watchdog timer as frequently as needed. Most other architectures do not meet that requirement, so long-running operations might result in a watchdog reset. This patch adds a generic udelay() function which takes care of resetting the watchdog before calling an architecture-specific __udelay(). Signed-off-by: Ingo van Lil <inguin@gmx.de>

| | | | | | | | | The board/armltd/integrator/split_by_variant.sh script used to print "Configuring for integrator*p board..." no matter which board name was being compiled.

* Fix all linker script to handle all rodata sectionsTrent Piepho2009-03-20-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A recent gcc added a new unaligned rodata section called '.rodata.str1.1', which needs to be added the the linker script. Instead of just adding this one section, we use a wildcard ".rodata*" to get all rodata linker section gcc has now and might add in the future. However, '*(.rodata*)' by itself will result in sub-optimal section ordering. The sections will be sorted by object file, which causes extra padding between the unaligned rodata.str.1.1 of one object file and the aligned rodata of the next object file. This is easy to fix by using the SORT_BY_ALIGNMENT command. This patch has not be tested one most of the boards modified. Some boards have a linker script that looks something like this: *(.text) . = ALIGN(16); *(.rodata) *(.rodata.str1.4) *(.eh_frame) I change this to: *(.text) . = ALIGN(16); *(.eh_frame) *(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*))) This means the start of rodata will no longer be 16 bytes aligned. However, the boundary between text and rodata/eh_frame is still aligned to 16 bytes, which is what I think the real purpose of the ALIGN call is. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>
