* MIPS: qemu-mips: use the unified u-boot.lds scriptGabor Juhos2013-01-31-70/+0
| | | | | | | | | | | | Remove the board specific linker script. It is not needed anymore, the unified MIPS linker script can be used instead. All qemu_mips targets are producing identical binary images after the change than before. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Cc: Daniel Schwierzeck <daniel.schwierzeck@googlemail.com>
* MIPS: remove OUTPUT_FORMAT from linker scriptsGabor Juhos2013-01-30-8/+0
| | | | | | | | | | | | | | | | The OUTPUT_FORMAT command in linker scripts was always misused due to some endianess and toolchain problems. Use GCC flags to ensure proper output format, and get rid of the OUTPUT_FORMAT commands in the board specific u-boot.lds files.

* MIPS: qemu-mips: add '-M mips' switch to the example usage commandGabor Juhos2013-01-16-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using the example command from the README file does not work as expected. qemu shows a text similar to the one below and it hangs. $ qemu-system-mips -L . -nographic Could not open option rom 'pxe-pcnet.rom': No such file or directory qemu-system-mips: pci_add_option_rom: failed to find romfile "vgabios-cirrus.bin" qemu: terminating on signal 15 from pid 19726 This happens because qemu emulates a Malta board by default if the machine type is not defined explicitely on the command line. For a working test, the '-M mips' switch is required: $ qemu-system-mips -M mips -L . -nographic Could not open option rom 'vgabios.bin': No such file or directory U-Boot 2013.01-rc2-00132-g1e8e648-dirty (Jan 08 2013 - 09:06:42) Board: Qemu -M mips CPU: 24Kf proc_id=0x19300 DRAM: 128 MiB ## Unknown flash on Bank 1 - Size = 0x00000000 = 0 MB Flash: 0 Bytes *** Warning - bad CRC, using default environment In: serial Out: serial Err: serial Net: NE2000 Hit any key to stop autoboot: 0 qemu-mips # Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Cc: Daniel Schwierzeck <daniel.schwierzeck@googlemail.com> Cc: Vlad Lungu <vlad.lungu@windriver.com>
* MIPS: qemu-mips: fix a typo in READMEGabor Juhos2013-01-16-1/+1
| | | | | | | | | | | | | | | | | The 'Limitations & comments' section refers to the '-m mips' switch which is not valid. The '-m' switch can be used for setting the virtual RAM size: $qemu-system-mips --help | grep '^-m ' -m megs set virtual RAM size to megs MB [default=128] $ The correct switch for specifying the machine type is '-M'.

* common: Discard the __u_boot_cmd sectionMarek Vasut2012-10-22-7/+0
| | | | | | | | | | | The command declaration now uses the new LG-array method to generate list of commands. Thus the __u_boot_cmd section is now superseded and redundant and therefore can be removed. Also, remove externed symbols associated with this section from include/command.h .

* ne2000: Convert to new net-multi model, fixes build of three boardsBernhard Kaindl2011-12-08-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the build of the two sh boards shmin and r7780mp and qemu-mips which currently fail to build due to dropped pre-CONFIG_NET_MULTI code. This v2 patch minimizes the number of lines in the diff for easy review and to eliminate any possible accidential changes resulting from moving lines of code in the file. This also makes the register function very easy. Any cleanups and improvements are intentionally deferred to follow-up patches to keep this patch as simple and as easy to review as possible. A new driver register function, ne2k_register() calls the existing one-time setup part of the old init function and calls eth_register(). Changes to shmin, r7780mp and qemu-mips: - Call the new ne2k_register() from board_eth_init() of the boards. - Tested using qemu-mips board, - Tested the two renesas / sh boards r7780mp and shmin to compile again, and should work. checkpatch-clean when "--ignore VOLATILE" is added to .checkpatch.conf, and no warnings introduced in none of the three boards using this driver.

* MIPS: Introduce --gc-sections for MIPSDaniel Schwierzeck2011-05-10-5/+5

* 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>
* Rename TEXT_BASE into CONFIG_SYS_TEXT_BASEWolfgang Denk2010-10-18-2/+2
| | | | | | | | | | | | The change is currently needed to be able to remove the board configuration scripting from the top level Makefile and replace it by a simple, table driven script. Moving this configuration setting into the "CONFIG_*" name space is also desirable because it is needed if we ever should move forward to a Kconfig driven configuration system.

* Fix all linker script to handle all rodata sectionsTrent Piepho2009-03-20-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A recent gcc added a new unaligned rodata section called '.rodata.str1.1', which needs to be added the the linker script. Instead of just adding this one section, we use a wildcard ".rodata*" to get all rodata linker section gcc has now and might add in the future. However, '*(.rodata*)' by itself will result in sub-optimal section ordering. The sections will be sorted by object file, which causes extra padding between the unaligned rodata.str.1.1 of one object file and the aligned rodata of the next object file. This is easy to fix by using the SORT_BY_ALIGNMENT command. This patch has not be tested one most of the boards modified. Some boards have a linker script that looks something like this: *(.text) . = ALIGN(16); *(.rodata) *(.rodata.str1.4) *(.eh_frame) I change this to: *(.text) . = ALIGN(16); *(.eh_frame) *(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*))) This means the start of rodata will no longer be 16 bytes aligned. However, the boundary between text and rodata/eh_frame is still aligned to 16 bytes, which is what I think the real purpose of the ALIGN call is. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>
* Align end of bss by 4 bytesSelvamuthukumar2008-11-18-1/+1
| | | | | | | | | | Most of the bss initialization loop increments 4 bytes at a time. And the loop end is checked for an 'equal' condition. Make the bss end address aligned by 4, so that the loop will end as expected. Signed-off-by: Selvamuthukumar <selva.muthukumar@e-coninfotech.com> Signed-off-by: Wolfgang Denk <wd@denx.de>
* Change initdram() return type to phys_size_tBecky Bruce2008-06-12-1/+1
| | | | | | | | | | | | | | | | | | | This patch changes the return type of initdram() from long int to phys_size_t. This is required for a couple of reasons: long int limits the amount of dram to 2GB, and u-boot in general is moving over to phys_size_t to represent the size of physical memory. phys_size_t is defined as an unsigned long on almost all current platforms. This patch *only* changes the return type of the initdram function (in include/common.h, as well as in each board's implementation of initdram). It does not actually modify the code inside the function on any of the platforms; platforms which wish to support more than 2GB of DRAM will need to modify their initdram() function code. Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc MPC8641HPCN. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>

* Use jr as register jump instructionShinya Kuribayashi2008-04-18-1/+1
| | | | | | | | | | Current assembler codes are inconsistent in the way of register jump instruction usage; some use jr, some use j. Of course GNU as allows both usages, but as can be expected from `Jump Register' the mnemonic `jr' is more intuitive than `j'. For example, Linux doesn't have `j <reg>' usage at all.
