* mx25: Fix boot hang by avoiding vector relocationFabio Estevam2015-01-08-0/+27
| | | | | | | | | | | | | | | | | | | | | Since commit 3ff46cc42b9d73d0 ("arm: relocate the exception vectors") mx25pdk hangs like this: CPU: Freescale i.MX25 rev1.2 at 399 MHz Reset cause: WDOG Board: MX25PDK I2C: ready DRAM: 64 MiB (hangs) Add a specific relocate_vectors macro that skips the vector relocation, as the i.MX25 SoC does not provide RAM at the high vectors address (0xFFFF0000), and (0x00000000) maps to ROM. This allows mx25 to boot again. Acked-By: Bill Pringlemeir <bpringlemeir@nbsps.com> Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>

* kbuild: move asm-offsets.c from SoC directory to arch/$(ARCH)/libMasahiro Yamada2014-03-28-57/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | U-Boot has supported two kinds of asm-offsets.h. One is generic for all architectures and its source is located at ./lib/asm-offsets.c. The other is SoC specific and its source is under SoC directory. The problem here is that only boards with SoC directory can use the asm-offsets infrastructure. Putting asm-offsets.c right under CPU directory does not work. Now a new demand is coming. PowerPC folks want to use asm-offsets. But no PowerPC boards have SoC directory. It seems inconsistent that some boards add asm-offsets.c to SoC directoreis and some to CPU directories. It looks more reasonable to put asm-offsets.c under arch/$(ARCH)/lib. This commit merges asm-offsets.c under SoC directories into arch/$(ARCH)/lib/asm-offsets.c. By the way, I doubt the necessity of some entries in asm-offsets.c. I am leaving refactoring to the board maintainers. Please check "TODO" in the comment blocks in arch/{arm,nds32}/lib/asm-offsets.c.

* mx25: Fix eSDHC supportBenoît Thébaudeau2012-10-15-9/+10
| | | | | | | | | | | | | | | | The MMC driver appropriate for the i.MX25 is fsl_esdhc, which has nothing to do with mxcmmc. Also, each eSDHC instance has a dedicated clock, so gd->sdhc_clk must be set accordingly. This is good for the case only a single SDHC instance is used (initialization made with fsl_esdhc_mmc_init()). A future patch will fix the multi-instance use case (initialization made directly with fsl_esdhc_initialize()).

* | 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>
