* ARM: fix the standalone programsJeroen Hofstee2013-12-12-2/+2
| | | | | | | | | | | | | | The standalone programs do not use the api calls, but rely directly on u-boot variable gd->jt for the jump table. Commit fe1378a - "ARM: use r9 for gd" changed the register holding the address of gd, but the assembly code in the standalone examples was not updated accordingly. This broke the programs on ARM relying on the jumptable in the v2013.10 release. This patch unbricks them by using the correct register.

* Revert "standalone-examples: support custom GCC lib"Tom Rini2013-09-12-13/+2
| | | | | | | | | | | | After further testing, this patch has two problems. First, examples/standalone/Makefile was already inherting PLATFORM_LIBS from the top-level Makefile so this lead to duplicating the private libgcc. Second, currently the private libgcc has a reference to 'hang' that is not being fulfilled. This reverts commit 4412db46468d5965da736d06f84d13e68a6e0b51. Signed-off-by: Tom Rini <trini@ti.com>

* Reduce build timesWolfgang Denk2011-11-03-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | U-Boot Makefiles contain a number of tests for compiler features etc. which so far are executed again and again. On some architectures (especially ARM) this results in a large number of calls to gcc. This patch makes sure to run such tests only once, thus largely reducing the number of "execve" system calls. Example: number of "execve" system calls for building the "P2020DS" (Power Architecture) and "qong" (ARM) boards, measured as: -> strace -f -e trace=execve -o /tmp/foo ./MAKEALL <board> -> grep execve /tmp/foo | wc -l Before: After: Reduction: ================================== P2020DS 20555 15205 -26% qong 31692 14490 -54% As a result, built times are significantly reduced, typically by 30...50%.

* examples: api: allow build with private libgccChe-liang Chiou2011-10-22-3/+1

This makes building examples/api break on certain boards that do not/cannot use the public libgcc. Nevertheless, this patch has to also touch the top-level Makefile to fix this problem because the current top-level Makefile does not specify libgcc as a prerequisite of examples/api, and explicitly builds examples/api _before_ libgcc. For testing this patch, I added the following to configs/seaboard.h and ran demo.bin on a Seaboard. +#define CONFIG_API +#define CONFIG_SYS_MMC_MAX_DEVICE 2 +#define CONFIG_CMD_NET +#define CONFIG_NET_MULTI Signed-off-by: Che-Liang Chiou <clchiou@chromium.org> Acked-by: Mike Frysinger <vapier@gentoo.org>

* Fix variable flavor in examples/standalone/MakefileChe-liang Chiou2011-05-12-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GNU Makefile have two flavors of variables, recursively expanded that is defined by using '=', and simply expanded that is defined by using ':='. The bug is caused by using recursively expanded flavor for BIN and SREC. As you can see below, they are prepended by $(obj) twice. We can reproduce this bug with a simplified version of this Makefile: $ cat >Makefile <<\EOF obj := /path/to/obj/ ELF := hello_world BIN_rec = $(addsuffix .bin,$(ELF)) # recursively expanded BIN_sim := $(addsuffix .bin,$(ELF)) # simply expanded ELF := $(addprefix $(obj),$(ELF)) BIN_rec := $(addprefix $(obj),$(BIN_rec)) BIN_sim := $(addprefix $(obj),$(BIN_sim)) show: @echo BIN_rec=$(BIN_rec) @echo BIN_sim=$(BIN_sim) .PHONY: show EOF $ make show BIN_rec=/path/to/obj//path/to/obj/hello_world.bin BIN_sim=/path/to/obj/hello_world.bin Signed-off-by: Che-Liang Chiou <clchiou@chromium.org>

* 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>
* examples/standalone: Use gcc's -fno-toplevel-reorderPeter Tyser2010-10-12-0/+5
| | | | | | | | | | | | | | | | Using -fno-toplevel-reorder causes gcc to not reorder functions. This ensures that an application's entry point will be the first function in the application's source file. This change, along with commit 620bbba524fbaa26971a5004793010b169824f1b should cause a standalone application's entry point to be at the base of the compiled binary. Previously, the entry point could change depending on gcc version and flags. Note -fno-toplevel-reorder is only available in gcc version 4.2 or greater.

In the standalone example 'smc911x_eeprom' the return value of smc911x_detect is interpreted in a different way (0 for error, !0 as OK). This leads to the error that the chip will not be detected.

* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-13/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) { ...

* examples/standalone: Remove relocation compile flags for PowerPCPeter Tyser2010-06-29-0/+10
| | | | | | | | | | | | | | | | | | | | Previously, standalone applications were compiled with gcc flags that produced relocatable executables on the PowerPC architecture (eg with the -mrelocatable and -fPIC flags). There's no reason for these applications to be fully relocatable at this time since no relocation fixups are performed on standalone applications. Additionally, removing the gcc relocation flags results in the entry point of applications residing at the base of the image. When a standalone application was relocatable, the entry point was generally located at an offset into the image which was confusing and prone to errors. This change moves the entry point of PowerPC standalone applications from 0x40004 (usually) to 0x40000. Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Wolfgang Denk <wd@denx.de>
