* kconfig: arm: introduce symbol for ARM CPUsGeorges Savoundararadj2014-10-29-33/+0
| | | | | | | | | | | | | | | | | This commit introduces a Kconfig symbol for each ARM CPU: CPU_ARM720T, CPU_ARM920T, CPU_ARM926EJS, CPU_ARM946ES, CPU_ARM1136, CPU_ARM1176, CPU_V7, CPU_PXA, CPU_SA1100. Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected for CPU_ARM1176 and CPU_V7. For each target, the corresponding CPU is selected and the definition of SYS_CPU in the corresponding Kconfig file is removed. Also, it removes redundant "string" type in some Kconfig files.

* MAINTAINERS: comment out blank M: fieldMasahiro Yamada2014-09-24-2/+2
| | | | | | | | | | | | | | | | | | Since commit ddaf5c8f3030050fcd356a1e49e3ee8f8f52c6d4 (patman: RunPipe() should not pipe stdout/stderr unless asked), Patman spits lots of "Invalid MAINTAINERS address: '-'" error messages for patches with global changes. It takes too long for Patman to process them. Anyway, "M: -" does not carry any important information. Rather, it is just like a place holder in case of assigning a new board maintainer. Let's comment out. This commit can be reproduced by the following command: find . -name MAINTAINERS | xargs sed -i -e '/^M:[[:blank:]]*-$/s/^/#/' Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

| | | | | | | | | | | | | | | | | | | | | | | | The "S: Orphan" in MAINTAINERS means that the maintainer in the "M:" field is unreachable (i.e. the email address is not working). (Refer to the definition of "Orphan" adopted in U-Boot in the log of commit 31f1b654b2f395b69faa5d0d3c1eb0803923bd3b, "boards.cfg: move boards with invalid emails to Orphan") For patch files adding global changes, scripts/get_maintainer.pl adds bunch of such invalid email addresses, which results in tons of annoying bounce emails.

* Add board MAINTAINERS filesMasahiro Yamada2014-07-30-0/+47
| | | | | | | | | | | | | | | | | | | | We have switched to Kconfig and the boards.cfg file is going to be removed. We have to retrieve the board status and maintainers information from it. The MAINTAINERS format as in Linux Kernel would be nice because we can crib the scripts/get_maintainer.pl script. After some discussion, we chose to put a MAINTAINERS file under each board directory, not the top-level one because we want to collect relevant information for a board into a single place. TODO: Modify get_maintainer.pl to scan multiple MAINTAINERS files.

* kconfig: add board Kconfig and defconfig filesMasahiro Yamada2014-07-30-0/+328
| | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds: - arch/${ARCH}/Kconfig provide a menu to select target boards - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig set CONFIG macros to the appropriate values for each board - configs/${TARGET_BOARD}_defconfig default setting of each board (This commit was automatically generated by a conversion script based on boards.cfg) In Linux Kernel, defconfig files are located under arch/${ARCH}/configs/ directory. It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.

* arm: Add support for semihosting for armv8 fastmodel targets.Darwin Rambo2014-07-03-5/+96
| | | | | | | | | | | | | | | | | | | | | | The armv8 ARM Trusted Firmware (ATF) can be used to load various ATF images and u-boot, and does this for virtual platforms by using semihosting. This commit extends this idea by allowing u-boot to also use semihosting to load the kernel/ramdisk/dtb. This eliminates the need for a bootwrapper and produces a more realistic boot sequence with virtual models. Though the semihosting code is quite generic, support for armv7 in fastmodel is less useful due to the wide range of available silicon and the lack of a free armv7 fastmodel, so this change contains an untested armv7 placeholder for the service trap opcode. Please refer to doc/README.semihosting for a more detailed description of semihosting and how it is used with the armv8 virtual platforms.

* 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>

| | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | This enables Vpp and disables the flash protection on the Integrator when starting U-Boot.

* 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.

* 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.

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.
