* 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>
* pci: Clean up PCI info when CONFIG_PCI_SCAN_SHOWPeter Tyser2010-11-14-64/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change does the following: - Removes the printing of the PCI interrupt line value. This is normally set to 0 by U-Boot on bootup and is rarely used during everyday operation. - Prints out the PCI function number of a device. Previously a device with multiple functions would be printed identically 2 times, which is generally confusing. For example, on an Intel 2 port gigabit Ethernet card the following was displayed: ... 04 01 8086 1010 0200 00 04 01 8086 1010 0200 00 ... - Prints a text description of each device's PCI class instead of the raw PCI class code. The textual description makes it much easier to determine what devices are installed on a PCI bus. - Changes the general formatting of the PCI device output. Previous output: PCIE1: connected as Root Complex 04 01 8086 1010 0200 00 04 01 8086 1010 0200 00 03 00 10b5 8112 0604 00 02 01 10b5 8518 0604 00 02 02 10b5 8518 0604 00 08 00 1957 0040 0b20 00 07 00 10b5 8518 0604 00 09 00 10b5 8112 0604 00 07 01 10b5 8518 0604 00 07 02 10b5 8518 0604 00 06 00 10b5 8518 0604 00 02 03 10b5 8518 0604 00 01 00 10b5 8518 0604 00 PCIE1: Bus 00 - 0b PCIE2: connected as Root Complex 0d 00 1957 0040 0b20 00 PCIE2: Bus 0c - 0d Updated output: PCIE1: connected as Root Complex 04:01.0 - 8086:1010 - Network controller 04:01.1 - 8086:1010 - Network controller 03:00.0 - 10b5:8112 - Bridge device 02:01.0 - 10b5:8518 - Bridge device 02:02.0 - 10b5:8518 - Bridge device 08:00.0 - 1957:0040 - Processor 07:00.0 - 10b5:8518 - Bridge device 09:00.0 - 10b5:8112 - Bridge device 07:01.0 - 10b5:8518 - Bridge device 07:02.0 - 10b5:8518 - Bridge device 06:00.0 - 10b5:8518 - Bridge device 02:03.0 - 10b5:8518 - Bridge device 01:00.0 - 10b5:8518 - Bridge device PCIE1: Bus 00 - 0b PCIE2: connected as Root Complex 0d:00.0 - 1957:0040 - Processor PCIE2: Bus 0c - 0d Signed-off-by: Peter Tyser <ptyser@xes-inc.com>

* Drop support for CONFIG_SYS_ARM_WITHOUT_RELOCWolfgang Denk2010-10-29-2/+0
| | | | | | | | | | | | | | | | When this define was introduced, the idea was to provide a soft migration path for ARM boards to get adapted to the new relocation support. However, other recent changes led to a different implementation (ELF relocation), where this no longer works. By now CONFIG_SYS_ARM_WITHOUT_RELOC does not only not help any more, but it actually hurts because it obfuscates the actual code by sprinkling it with lots of dead and non-working debris. So let's make a clean cut and drop CONFIG_SYS_ARM_WITHOUT_RELOC. Signed-off-by: Wolfgang Denk <wd@denx.de> Tested-by: Heiko Schocher <hs@denx.de> Tested-by: Reinhard Meyer <u-boot@emk-elektronik.de>

* Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated valueWolfgang Denk2010-10-26-1/+1
| | | | | | | | | | | | | | | | | | 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.

* hwconfig: Utilize getenv_f before relocation to allow for larger bufferKumar Gala2010-10-23-1/+20
| | | | | | | | | | | | | | | | Since we use hwconfig in cases before relocation (like getting DDR params on FSL PPC systems), we can have strings that exceed the early small (32 byte) buffer size that getenv will handle. So we explicitly allocate our own buffer on the stack and use if to handle getting the hwconfig env string. We currently utilize a string length of 128 bytes. This allows us to get rid of boot messages like: env_buf too small [32] Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* always relocate fdt into an lmb-allocated memory blockTimur Tabi2010-10-20-55/+28
| | | | | | | | | | | | | | | | | | | | | The device tree (fdt) must always exist in within the bootmap (usually the first 16MB of RAM). If it doesn't, then boot_relocate_fdt() will allocate an LMB region in the bootmap and copy the fdt into that region. It will also increase the size of the fdt. If the fdt is already in the bootmap, then previously the memory was just reserved. There was no contingency if the reservation failed, however. By always allocating an lmb region and copying/resizing the fdt into that region, the code is simplified and the memory region is always allocated properly. Also change the types of some variables to avoid some typecasts.

In the case where boot_get_fdt returns an error bootm_start returns and the platform specific do_bootm_linux routines will never get called. Also only check argv[3] for an fdt addr if argc > 3 first.

For the case where the blob needs to be relocated, space is allocated inside the bootmap by calling lmb_alloc_base with size passed in plus some padding: of_len = *of_size + CONFIG_SYS_FDT_PAD; For the case where the blob is already inside the bounds of the boot map area, lmb_reserve is called to reserve the the space where the blob is already residing. The calculation for this case is currently: of_len = (CONFIG_SYS_BOOTMAPSZ + bootmap_base) - (ulong)fdt_blob; This is wrong because it reserves all the space in the boot map area from the blob to the end ignoring completely the actual size. The worst case is where the blob is at the beginning and the entire boot map area get reserved. Fix this by changing the length calculation to this: of_len = *of_size + CONFIG_SYS_FDT_PAD; This bug has likely never manifested itself because bootm has never been called with the fdt blob already in the bootmap area. In my testing on an OMAP3 beagle board I initially worked around the bug by simply moving the initial location of the fdt blob. I have tested with the new calculation with the fdt blob both inside and outside the boot map area. Signed-off-by: John Rigby <john.rigby@linaro.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces the 'spread' sub-command of the mtdparts command. This command will modify the existing mtdparts variable by increasing the size of the partitions such that 1) each partition's net size is at least as large as the size specified in the mtdparts variable and 2) each partition starts on a good block. The new subcommand is implemented by iterating over the mtd device partitions and collecting a bad blocks count in each -- including any trailing bad blocks -- and then modifying that partitions's part_info structure and checking if the modification affects the next partition. This patch is based on a port of the 'dynnamic partitions' feature by Harald Welte <laforge@gnumonks.org>; ported from commit e05835df019027391f58f9d8ce5e1257d6924798 of git://git.openmoko.org/u-boot.git. Whereas Harald's feature used a compile-time array to specify partitions, the feature introduced by this patch uses the mtdparts environment variable.

| | | | | | | | | | | | | | | | | | | | | | | | The get_mtd_device_nm function is called in a couple places and the string that is passed to it is not really used after the calls. This patch regroups the calls to this function into a new function, get_mtd_info.

| | | | | | | | | | | | | | | | | | The dump command is made to increment its address on repeat, as md does. Other commands do not make sense to issue repeatedly, and can be irritating when it happens accidentally, so don't.

* | nand erase: .spread, .part, .chip subcommandsScott Wood2010-10-11-6/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A while back, in http://lists.denx.de/pipermail/u-boot/2009-June/054428.html, Michele De Candia posted a patch to not count bad blocks toward the requested size to be erased. This is desireable when you're passing in something like $filesize, but not when you're trying to erase a partition. Thus, a .spread subcommand (named for consistency with http://lists.denx.de/pipermail/u-boot/2010-August/075163.html) is introduced to make explicit the user's desire to erase for a given amount of data, rather than to erase a specific region of the chip. While passing $filesize to "nand erase" is useful, accidentally passing something like $fliesize currently produces quite unpleasant results, as the variable evaluates to nothing and U-Boot assumes that you want to erase the entire rest of the chip/partition. To improve the safety of the erase command, require the user to make explicit their intentions by using a .part or .chip subcommand. This is an incompatible user interface change, but keeping compatibility would eliminate the safety gain, and IMHO it's worth it. While touching nand_erase_opts(), make it accept 64-bit offsets and sizes, fix the percentage display when erase length is rounded up, eliminate an inconsistent warning about rounding up the erase length which only happened when the length was less than one block (rounding up for $filesize is normal operation), and add a diagnostic if there's an attempt to erase beginning at a non-block boundary.
