* usb: replace wait_ms() with mdelay()Mike Frysinger2012-03-19-3/+3
| | | | | | | | | | | | | | | | | | | | | | | Common code has a mdelay() func, so use that instead of the usb-specific wait_ms() func. This also fixes the build errors: ohci-hcd.c: In function 'submit_common_msg': /usr/local/src/u-boot/blackfin/include/usb.h:202:44: sorry, unimplemented: inlining failed in call to 'wait_ms': function body not available ohci-hcd.c:1519:9: sorry, unimplemented: called from here /usr/local/src/u-boot/blackfin/include/usb.h:202:44: sorry, unimplemented: inlining failed in call to 'wait_ms': function body not available ohci-hcd.c:1816:10: sorry, unimplemented: called from here /usr/local/src/u-boot/blackfin/include/usb.h:202:44: sorry, unimplemented: inlining failed in call to 'wait_ms': function body not available ohci-hcd.c:1827:10: sorry, unimplemented: called from here /usr/local/src/u-boot/blackfin/include/usb.h:202:44: sorry, unimplemented: inlining failed in call to 'wait_ms': function body not available ohci-hcd.c:1844:10: sorry, unimplemented: called from here /usr/local/src/u-boot/blackfin/include/usb.h:202:44: sorry, unimplemented: inlining failed in call to 'wait_ms': function body not available ohci-hcd.c:1563:11: sorry, unimplemented: called from here /usr/local/src/u-boot/blackfin/include/usb.h:202:44: sorry, unimplemented: inlining failed in call to 'wait_ms': function body not available ohci-hcd.c:1583:9: sorry, unimplemented: called from here make[1]: *** [ohci-hcd.o] Error 1 Signed-off-by: Mike Frysinger <vapier@gentoo.org> Acked-by: Marek Vasut <marex@denx.de>

* PPC405EX CHIP_21 erratumSteven A. Falco2011-05-12-0/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | APM errata CHIP_21 for the 405EX/EXr (from the rev 1.09 document dated 4/27/11) states that rev D processors may wake up with the wrong feature set. This patch implements the APM-proposed workaround. To enable this patch for your board, add the appropriate define for your CPU to your board header file. See kilauea.h for more information. The following variants are supported: #define CONFIG_SYS_4xx_CHIP_21_405EX_NO_SECURITY #define CONFIG_SYS_4xx_CHIP_21_405EX_SECURITY #define CONFIG_SYS_4xx_CHIP_21_405EXr_NO_SECURITY #define CONFIG_SYS_4xx_CHIP_21_405EXr_SECURITY Please note that if you select the wrong define, your board will not boot, and JTAG will be required to recover.

| | | | | | | | | | | | | -msingle-pic-base is a new gcc option for ppc and it reduces the size of my u-boot with 6-8 KB. While at it, add -fno-jump-tables too to save a few more bytes. -msingle-pic-base will be in gcc 4.6, however backported patches are available at http://bugs.gentoo.org/show_bug.cgi?id=347281 Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se>

* arch/powerpc/*/config.mk: make CONFIG_SYS_LDSCRIPT settings workWolfgang Denk2010-11-26-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | As we try to get rid of board specific config.mk files we must provide a way for board specific settings of the LDSCRIPT variable (path to the linker script) where needed. We now implement the following hierarchy: - Highest priority has a "#define CONFIG_SYS_LDCONFIG" in the board config file. - If CONFIG_SYS_LDCONFIG is not set, and the system is booting from NAND (CONFIG_NAND_SPL is set), then a board specific linker script board/$(BOARDDIR)/u-boot-nand.lds gets used. - If we are not booting from NAND, we test if a processor specific linker script arch/powerpc/cpu/$(CPU)/u-boot.lds exists; if so we use that. - As default, arch/powerpc/config.mk gets used.

* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* PowerPC: Don't destroy fixup table while doing fixupsJoakim Tjernlund2010-11-14-1/+1
| | | | | | | | | The fixup procedure just stored a constant value in the fixup table rather than just adjusting the table. Although that doesn't seem to do any harm, it prevents relocation more that once. Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se>
* Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated valueWolfgang Denk2010-10-26-1/+2
| | | | | | | | | | | | | | | | | | CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not being able to use "sizeof(struct global_data)" in assembler files. Recent experience has shown that manual synchronization is not reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into GENERATED_GBL_DATA_SIZE which gets automatically generated by the asm-offsets tool. In the result, all definitions of this value can be deleted from the board config files. We have to make sure that all files that reference such data include the new <asm-offsets.h> file. No other changes have been done yet, but it is obvious that similar changes / simplifications can be done for other, related macro definitions as well.

* Rename CONFIG_SYS_INIT_RAM_END into CONFIG_SYS_INIT_RAM_SIZEWolfgang Denk2010-10-26-11/+11
| | | | | | | | | | | | | | | | | | CONFIG_SYS_INIT_RAM_END was a misnomer as it suggests this might be some end address; to make the meaning more clear we rename it into CONFIG_SYS_INIT_RAM_SIZE No other code changes are performed in this patch, only minor editing of white space (due to the changed length) and the comments was done, where noticed. Note that the code for the PATI and cmi_mpc5xx board configurations looks seriously broken.

* powerpc: do not fixup NULL ptrsJoakim Tjernlund2010-10-18-1/+3
| | | | | | | | | | | | | | The fixup routine must not fixup NULL pointers. Problem can be seen by char *testfun(void) __attribute__((weak)); char *(*myfun)(void) = testfun; Then add printf("myfun:%p, &myfun:%p\n", myfun, &myfun); before relocation and after relocation. myfun should be NULL in both cases but it is not.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default the trace broadcast is enabled on 44x systems. To reduce power consumption when instruction tracing is not needed, disable trace broadcast. Check External Debug Mode (EDM) bit to detect if it should be disabled or not. Resetting system via a debugger will set the DBCR0[EDM] bit. Resetting via u-boot or OS will not. Signed-off-by: Victor Gallardo <vgallardo@apm.com> Signed-off-by: Stefan Roese <sr@denx.de>
| * ppc4xx: Cleanup of PVR detection code in cpu.cStefan Roese2010-09-23-71/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch cleans the PVR detection code in check_cpu() up a bit. Basically the strings are better seperated, resulting in an easier to understand and maintain code version. The #ifdef's couldn't be removed easily because of two reasons: - Some SoC revisions have the same PVR, so need a way to differentiate between those two SoC's. - In some case statements registers only available in this SoC variant are referenced. Instead I moved the CONFIG_440 #ifdef a bit, so that 405 platforms don't add this 440 detection code and vice versa. Resulting in this U-Boot image size change: 405EX (Kilauea): 408 bytes less 440EPx (Sequoia): 604 bytes less 460EX (Canyonlands): 564 bytes less Signed-off-by: Stefan Roese <sr@denx.de> Cc: Wolfgang Denk <wd@denx.de>
| * ppc4xx: Use common NS16550 driver for PPC4xx UARTStefan Roese2010-09-23-698/+123
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the PPC4xx UART driver. Instead the common NS16550 driver is used, since all PPC4xx SoC's use this peripheral device. The file 4xx_uart.c now only implements the UART clock calculation function which also sets the SoC internal UART divisors. All PPC4xx board config headers are changed to use this common NS16550 driver now. Tested on these boards: acadia, canyonlands, katmai, kilauea, sequoia, zeus Signed-off-by: Stefan Roese <sr@denx.de>
| * ppc4xx: Big header cleanup part 2, mostly PPC405 relatedStefan Roese2010-09-23-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This cleanup is done by creating header files for all SoC versions and moving the SoC specific defines into these special headers. This way the common header ppc405.h and ppc440.h can be cleaned up finally. As a part from this cleanup, the GPIO definitions for PPC405EP are corrected. The high and low parts of the registers (for example CONFIG_SYS_GPIO0_OSRL vs. CONFIG_SYS_GPIO0_OSRH) have been defined in the wrong order. This patch now fixes this issue by switching these xxxH and xxxL values. This brings the GPIO 405EP port in sync with all other PPC4xx ports. Signed-off-by: Stefan Roese <sr@denx.de>
