* integrator: remove fragile delay loop from PCI codeLinus Walleij2012-03-04-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | The reference implementation of the PCI initialization code almost everywhere contain this fragile loop of "a few usecs", and its use of volatile variables to delay a number of bus cycles is indeed uncertain. Reading the manual "Integrator/AP Users Guide", page 5-15 it is clearly stated: "Wait until 230ms after the end of the reset period before accessing V360EPC internal registers. The V360EPC supports the use of a serial configuration PROM and the software must wait for the device to detect the absence of this PROM before accessing any registers. The required delay is a function of the PCI Clock, but at the lower frequency (25MHz) is 230ms". So let's simply wait 230ms per the spec. This solves the compilation error that looked like this: pci.c: In function ‘pci_init_board’: pci.c:286:18: warning: variable ‘j’ set but not used Reported-by: Wolfgang Denk <wd@denx.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* integrator: rewrite the AP PCI driverLinus Walleij2012-02-27-250/+532
| | | | | | | | | | | | | | | | | | | | | | | | | The PCI support for the Integrator AP has apparently never been finished and I strongly suspect that it has never worked, so let's fix it. This is a list of the more or less un-splittable changes done in this driver rewrite: - Replace the register definitions stashed into the config file (!) with a copy if the register file from the Linux kernels arch/arm/include/asm/hardware/pci_v3.h - Delete the unreadable gigantic macros that perform the config accesses and replace them with copyedited code from Linux arch/arm/mach-integrator/pci_v3.c - Rewrite the rest of the setup code to use the v3_[read|write][lwb]() accessors. - Enable PCI by default in the AP board configuration. - Fix checkpatch warnings and make code more conformant.

* integrator: stop calling pci_init() twiceLinus Walleij2012-02-27-3/+0
| | | | | | | | The U-Boot startup infrastructure already makes sure pci_init() is called at a proper time, calling it again from within the board setup code will not make things better. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* 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: 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.

* 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>

* 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.

* 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.

* 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>
