* Blackfin: dont reset SWRST on newer bf526 partsMike Frysinger2011-07-12-1/+3
| | | | | | | The bug in the BF526 rom when doing a software reset exists only in older silicon versions, so don't clear SWRST on newer parts. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: uart: add multiple serial supportMike Frysinger2011-07-12-55/+210
| | | | | | | This brings CONFIG_SERIAL_MULTI support to the Blackfin on-chip UARTs. Ends up adding only ~512bytes per additional UART. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: uart: move debug buffers into local bssMike Frysinger2011-07-12-8/+3
| | | | | | | There's no need for these saved buffers to be global symbols, or in the data section. So mark them static to move them into the bss. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: use on-chip reset func with newer partsMike Frysinger2011-06-03-36/+34
| | | | | | | | Turns out the documentation is wrong and doing "RAISE 1" does not result in a software reset, only a core reset. So when the on-chip rom has a functioning reset helper, use it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: use common LDSCRIPT logicMike Frysinger2011-06-03-4/+0
| | | | | | | | Now that common code is a bit smarter when it comes to default LDSCRIPT values, rename the default Blackfin file and drop the Blackfin-specific config.mk logic. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* gpio: generalize for all generic gpio providersMike Frysinger2011-04-13-119/+53
| | | | | | | | | | | | The Blackfin gpio command isn't terribly Blackfin-specific. So generalize the few pieces into two new optional helpers: name_to_gpio() - turn a string name into a GPIO # gpio_status() - display current pin bindings (think /proc/gpio) Once these pieces are pulled out, we can relocate the cmd_gpio.c into the common directory.

* Make STANDALONE_LOAD_ADDR configurable per boardWolfgang Denk2011-04-12-1/+1
| | | | | | | | | | | | | Rename STANDALONE_LOAD_ADDR into CONFIG_STANDALONE_LOAD_ADDR and allow that the architecture-specific default value gets overwritten by defining the value in the board header file.

* Blackfin: replace "bfin_reset_or_hang()" with "panic()"Kyle Moffett2011-04-08-19/+2
| | | | | | | | | | | The bfin_reset_or_hang function unnecessarily duplicates the panic() logic based on CONFIG_PANIC_HANG. This patch deletes 20 lines of code and just calls panic() instead. This also makes the following generic-restart conversion patch simpler. Signed-off-by: Kyle Moffett <Kyle.D.Moffett@boeing.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: bootrom.h: sync with toolchainMike Frysinger2011-04-08-27/+59
| | | | | | We need the updated LDR bit defines for our LDR utils. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: default to L1 bank A when L1 bank B does not existMike Frysinger2011-04-08-3/+7
| | | | | | | Some parts lack Bank B in L1 data, so have the linker script fall back to Bank A when that happens. This way we can still leverage L1 data. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: turn off caches when self initializingMike Frysinger2011-04-08-12/+33
| | | | | | | | | | | | | | When bootstrapping ourselves on the fly at runtime (via "go"), we need to turn off the caches to avoid taking software exceptions. Since caches need CPLBs and CPLBs need exception handlers, but we're about to rewrite the code in memory where those exception handlers live, we need to turn off caches first. This new code also encourages a slight code optimization by storing the MMR bases in dedicated registers so we don't have to fully load up the pointer regs multiple times.

* Blackfin: only check for os log when we have external memoryMike Frysinger2011-04-08-1/+1
| | | | | | | | If the part has no external memory configured, then there will be no os log for us to check, and any attempt to access that memory will trigger hardware errors. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: drop duplicate system mmr and L1 scratch definesMike Frysinger2011-04-08-42/+1
| | | | | | | Common code already takes care of setting up these defines when a port hasn't specified them, so punt the duplicate values. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: fix bd_t handlingMike Frysinger2011-04-08-9/+6
| | | | | | | | | The recent global data changes (making the size autogenerated) broke the board info handling on Blackfin ports as we were lying and lumping the bd_t size in with the gd_t size. So use the new dedicated bd_t size to setup its own address in memory. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: bf537: fix L1 data definesMike Frysinger2011-04-08-1/+1
| | | | | | | The __BFIN_DEF_ADSP_BF537_proc__ define isn't setup anymore, so use the one coming from the compiler. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: move CONFIG_BFIN_CPU back to board config.hMike Frysinger2011-04-08-2/+13
| | | | | | This is a revert of 821ad16fa9900c as Wolfgang doesn't like the new code. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: drop CONFIG_SYS_TEXT_BASE from boardsMike Frysinger2011-04-08-0/+4
| | | | | | | We don't want/use this value for Blackfin boards, so punt it and have the common code error out when people try to use it. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Introduce a new linker flag LDFLAGS_FINALHaiying Wang2011-03-22-1/+1
| | | | | | | | | | | | | | | commit 8aba9dceebb14144e07d19593111ee3a999c37fc Divides variable of linker flags to LDFLAGS-u-boot and LDFLAGS breaks the usage of --gc-section to build nand_spl. We still need linker option --gc-section for every uboot image, not only the main one. LDFLAGS_FINAL passes the --gc-sections to each uboot image. To get the proper linker flags, we use LDFLAGS and LDFLAGS_FINAL to replace PLATFORM_LDFLAGS in the Makefile of each nand_spl board.

* Divides variable of linker flags to LDFLAGS-u-boot and LDFLAGSNobuhiro Iwamatsu2011-01-25-1/+2
| | | | | | | | | | Linker needs to use the proper endian/bfd flags even when doing partial linking. LDFLAGS_u-boot sets linker option which is called it when U-boot is built (u-boot final). LDFLAGS sets necessary option by partial linking (use in cmd_link_o_target). CC: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
* Move DECLARE_GLOBAL_DATA_PTR to file scopeJohn Rigby2010-12-21-1/+2
| | | | | | | | | | | | | | | It can be optimised out by the compiler otherwise resulting in obscure errors like a board not booting. This has been documented in README since 2006 when these were first fixed up for GCC 4.x. Signed-off-by: John Rigby <john.rigby@linaro.org> Fix some additional places.

* Blackfin: drop initcode.o from combined objectMike Frysinger2010-11-19-4/+0
| | | | | | | | | We explicitly link in the initcode.o in the Blackfin linker script, so there is no need to merge it into the main common object for the linker to pull in itself. This also fixes duplicate symbol errors with the new partial linking logic. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: make sure bss len is multiple of 4 bytesMike Frysinger2010-11-18-0/+1
| | | | | | | | | | The Blackfin on-chip BootROM requires that fill operations (which is used for the bss) be aligned to 4 bytes (base addr and total len). Plus, the Blackfin early init asm code assumes the same thing. So rather than making things work for no real gain, make sure the bss len is padded to 4 bytes in the linker script. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: stick ins/outs funcs into their own .text sectionMike Frysinger2010-11-18-0/+5
| | | | | | | This lets the linker garbage collect these functions when they aren't actually used by placing them into the standard .text.<func> section. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * Blackfin: config.mk: drop manual stripping of config varsMike Frysinger2010-10-27-2/+0
| | | | | | | | | | | | | | | | Now that the common code takes care of stripping away quotes and such from numeric options, we no longer need to do so ourselves. So drop the custom code we have in the Blackfin config.mk. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
| * Blackfin: fix building after asm-offsets.h introMike Frysinger2010-10-27-0/+3
| | | | | | | | | | | | | | | | Since some of the defines in our config.h use the generated defines, we need to include the generated header. This fixes building of the Blackfin start.S file (where the stack is setup). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* | Replace CONFIG_RELOC_FIXUP_WORKS by CONFIG_NEEDS_MANUAL_RELOCWolfgang Denk2010-10-29-3/+0
|/ | | | | | | | | | | By now, the majority of architectures have working relocation support, so the few remaining architectures have become exceptions. To make this more obvious, we make working relocation now the default case, and flag the remaining cases with CONFIG_NEEDS_MANUAL_RELOC.

* Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated valueWolfgang Denk2010-10-26-7/+4
| | | | | | | | | | | | | | | | | | 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.

* Blackfin: propagate target cpu defines when building embedded envMike Frysinger2010-10-02-0/+3
| | | | | | | | | | | Since we're no longer extracting the env from the target ELF file (since upstream wouldn't take that change), we're back to the problem of cpu defines not properly propagating to the env setup stage. So the embedded env built by the host compiler doesn't match the one that is linked into the u-boot env. Reported-by: Vivi Li <vivi.li@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: cmd_gpio: accept upper case pin namesMike Frysinger2010-10-02-2/+3

* Blackfin: cmd_gpio: document/extend input sub-optionMike Frysinger2010-10-02-14/+13

* Blackfin: move CONFIG_BFIN_CPU to board config.mkMike Frysinger2010-10-02-9/+2
| | | | | | | | | The CONFIG_BFIN_CPU option is largely used in the build system, so move it out of the board config.h and into the board config.mk. It'd be nice to keep everything in the config.h, but the patch to extract that value early was rejected. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
