* 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>

* ARM: compiler options cleanup - improve tool chain supportWolfgang Denk2009-08-21-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* stdio/device: rework function naming conventionJean-Christophe PLAGNIOL-VILLARD2009-07-18-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far the console API uses the following naming convention: ======Extract====== typedef struct device_t; int device_register (device_t * dev); int devices_init (void); int device_deregister(char *devname); struct list_head* device_get_list(void); device_t* device_get_by_name(char* name); device_t* device_clone(device_t *dev); ======= which is too generic and confusing. Instead of using device_XX and device_t we change this into stdio_XX and stdio_dev This will also allow to add later a generic device mechanism in order to have support for multiple devices and driver instances.

* Eliminated arch-specific mmc header requirementAndy Fleming2009-02-16-0/+191
| | | | | | | | | | The current MMC infrastructure relies on the existence of an arch-specific header file. This isn't necessary, and a couple drivers were forced to implement dummy files to meet this requirement.

* MMC: Consolidate MMC/SD command definitionsHaavard Skinnemoen2008-06-28-4/+7
| | | | | | | | | | | | | | | This moves the MMC and SD Card command definitions from include/asm/arch/mmc.h into include/mmc.h. These definitions are given by the MMC and SD Card standards, not by any particular architecture. There's a lot more room for consolidation in the MMC drivers which I'm hoping to get done eventually, but this patch is a start. Compile-tested for all avr32 boards as well as lpc2292sodimm and lubbock. This should cover all three mmc drivers in the tree. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>

| | | | | | | | | | | | | | | | | | | | | | | The pxa255_idp being an old unmaintained board showed several issues: 1. CONFIG_INIT_CRITICAL was still defined. 2. Neither CONFIG_MAC_PARTITION nor CONFIG_DOS_PARTITION was defined. 3. Symbol flash_addr was undeclared. 4. The boards lowlevel_init function was still called memsetup. 5. The TEXT_BASE was still 0xa3000000 rather than 0xa3080000. 6. Using -march=armv5 instead of -march=armv5te resulted in lots of 'target CPU does not support interworking' warnings on recent compilers. 7. The PXA's serial driver redefined FFUART, BTUART and STUART used as indexes rather than the register definitions from the pxa-regs header file. Renamed them to FFUART_INDEX, BTUART_INDEX and STUART_INDEX to avoid any ambiguities. 8. There were several redefinition warnings concerning ICMR, OSMR3, OSCR, OWER, OIER, RCSR and CCCR in the PXA's assembly start file. 9. The board configuration file was rather outdated. 10. The part header file defined the vendor, product and revision arrays as unsigned chars instead of just chars in the block_dev_desc_t structure. Signed-off-by: Marcel Ziswiler <marcel@ziswiler.com>
