* treewide: replace #include <asm/errno.h> with <linux/errno.h>Masahiro Yamada2016-09-23-2/+2
| | | | | | | | | | | Now, arch/${ARCH}/include/asm/errno.h and include/linux/errno.h have the same content. (both just wrap <asm-generic/errno.h>) Replace all include directives for <asm/errno.h> with <linux/errno.h>.

* common: Pass the boot device into spl_boot_mode()Marek Vasut2016-06-26-1/+1
| | | | | | | | | | | | | | | | | | The SPL code already knows which boot device it calls the spl_boot_mode() on, so pass that information into the function. This allows the code of spl_boot_mode() avoid invoking spl_boot_device() again, but it also lets board_boot_order() correctly alter the behavior of the boot process. The later one is important, since in certain cases, it is desired that spl_boot_device() return value be overriden using board_boot_order().

* mx35: Fix boot hang by avoiding vector relocationFabio Estevam2015-03-02-0/+27
| | | | | | | | | | | | | | | Since commit 3ff46cc42b9d73d0 ("arm: relocate the exception vectors") mx35 does not boot anymore. Add a specific relocate_vectors macro that skips the vector relocation, as the i.MX35 SoC does not provide RAM at the high vectors address (0xFFFF0000), and (0x00000000) maps to ROM. This allows mx35 to boot again. Cc: Sebastian Priebe <sebastian.priebe@cadcon.de> Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Tested-by: Stefano Babic <sbabic@denx.de>

* arm: mx35: use common timer functionsAndrew Ruder2014-09-16-83/+0
| | | | | | | | | | | | | | | | | This patch moves mx35 to the common timer functions added in commit 8dfafdd - Introduce common timer functions <Rob Herring> The (removed) mx35 timer code (specifically __udelay()) could deadlock at the 32-bit boundary of get_ticks(). get_ticks() returned a 32-bit value cast up to a 64-bit value. If get_ticks() + tmo in __udelay() crossed the 32-bit boundary, the while condition became unconditionally true and locks the processor. Rather than patch the specific mx35 issues, simply move everything over to the common code.

* kbuild: move asm-offsets.c from SoC directory to arch/$(ARCH)/libMasahiro Yamada2014-03-28-71/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | U-Boot has supported two kinds of asm-offsets.h. One is generic for all architectures and its source is located at ./lib/asm-offsets.c. The other is SoC specific and its source is under SoC directory. The problem here is that only boards with SoC directory can use the asm-offsets infrastructure. Putting asm-offsets.c right under CPU directory does not work. Now a new demand is coming. PowerPC folks want to use asm-offsets. But no PowerPC boards have SoC directory. It seems inconsistent that some boards add asm-offsets.c to SoC directoreis and some to CPU directories. It looks more reasonable to put asm-offsets.c under arch/$(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.

* MX35: add support for woodburn boardStefano Babic2012-10-26-0/+138
| | | | | | | | | | | | | | | | | | | | | The woodburn board is based on the MX35 SOC. Support for both external (NOR) and internal (SD Card) boot mode are added. It uses the generic SPL framework to implement the internal boot mode. The following peripherals are supported: - Ethernet (FEC) - SD Card - NAND (512 MB) - NOR Flash In the internal boot mode, a simple imximage header is generated to set the address in internal RAM where the SOC must copy the SPL code. The initial setup is then demanded to the SPL itself. Signed-off-by: Stefano Babic <sbabic@denx.de>

* mx35: Fix eSDHC clocksBenoît Thébaudeau2012-10-16-2/+12
| | | | | | | | | | | | | | Each eSDHC instance has a dedicated clock. gd->sdhc_clk must also 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()).
