* board: sandburst: delete FORCEBUILDMasahiro Yamada2014-02-19-10/+2
| | | | | | | | | | | | | | | We had switched to Kbuild, so we do not need to delete sandburst board files at every build. U-Boot conventional build system did not check the update of command line option, -DBUILDUSER. Kbuild can handle it nicely and re-builds object files when command line options are changed. (The file ".*.cmd" stores the information how the file was generated at the previous build.) Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* kbuild: use Linux Kernel build scriptsMasahiro Yamada2014-02-19-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Now we are ready to switch over to real Kbuild. This commit disables temporary scripts: scripts/{Makefile.build.tmp, Makefile.host.tmp} and enables real Kbuild scripts: scripts/{Makefile.build,Makefile.host,Makefile.lib}. This switch is triggered by the line in scripts/Kbuild.include -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj We need to adjust some build scripts for U-Boot. But smaller amount of modification is preferable. Additionally, we need to fix compiler flags which are locally added or removed. In Kbuild, it is not allowed to change CFLAGS locally. Instead, ccflags-y, asflags-y, cppflags-y, CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o are prepared for that purpose.

* Refactor linker-generated arraysAlbert ARIBAUD2013-03-12-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | Refactor linker-generated array code so that symbols which were previously linker-generated are now compiler- generated. This causes relocation records of type R_ARM_ABS32 to become R_ARM_RELATIVE, which makes code which uses LGA able to run before relocation as well as after. Note: this affects more than ARM targets, as linker- lists span possibly all target architectures, notably PowerPC.

| | | | | | | | | | The top level Makefile does not do any recursion into subdirs when cleaning, so these clean/distclean targets in random arch/board dirs never get used. Punt them all.

* 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>
* Makefile: move all Power Architecture boards into boards.cfgWolfgang Denk2010-10-18-12/+0
| | | | | | | | | | Clean up Makefile, and drop a lot of the config.mk files on the way. We now also automatically pick all boards that are listed in boards.cfg (and with all configurations), so we can drop the redundant entries from MAKEALL to avoid building these twice.

* Rename TEXT_BASE into CONFIG_SYS_TEXT_BASEWolfgang Denk2010-10-18-4/+4
| | | | | | | | | | | | 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.

* ppc4xx: Use common NS16550 driver for PPC4xx UARTStefan Roese2010-09-23-0/+2
| | | | | | | | | | | | | | | | 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>

* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hush shell dynamically allocates (and re-allocates) memory for the argument strings in the "char *argv[]" argument vector passed to commands. Any code that modifies these pointers will cause serious corruption of the malloc data structures and crash U-Boot, so make sure the compiler can check that no such modifications are being done by changing the code into "char * const argv[]". This modification is the result of debugging a strange crash caused after adding a new command, which used the following argument processing code which has been working perfectly fine in all Unix systems since version 6 - but not so in U-Boot: int main (int argc, char **argv) { while (--argc > 0 && **++argv == '-') { /* ====> */ while (*++*argv) { switch (**argv) { case 'd': debug++; break; ... default: usage (); } } } ... } The line marked "====>" will corrupt the malloc data structures and usually cause U-Boot to crash when the next command gets executed by the shell. With the modification, the compiler will prevent this with an error: increment of read-only location '*argv' N.B.: The code above can be trivially rewritten like this: while (--argc > 0 && **++argv == '-') { char *arg = *argv; while (*++arg) { switch (*arg) { ...

| * ppc4xx: TLB init file cleanupStefan Roese2010-04-19-112/+20
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds new macros, with frequently used combinations of the 4xx TLB access control and storage attibutes. Additionally the 4xx init.S files are updated to make use of these new macros. Resulting in easier to read TLB definitions. Additionally some init.S files are updated to use the mmu header for the TLB defines, instead of defining their own macros. Signed-off-by: Stefan Roese <sr@denx.de>

|/ | | | | | | | | | | | | | | | | As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure.

* Fix all linker script to handle all rodata sectionsTrent Piepho2009-03-20-6/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
