* treewide: replace #include <asm/errno.h> with <linux/errno.h>Masahiro Yamada2016-09-23-1/+1
| | | | | | | | | | | 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>.

* imx: mxs: reimplement get_cpu_revPeng Fan2015-09-02-28/+24
| | | | | | | | | | | | Rewrite get_cpu_rev, from "static const char *get_cpu_rev(void)" to "u32 get_cpu_rev(void)". To align with get_cpu_rev of other i.MXes. Also write get_imx_type to replace get_cpu_type, since we have macro named get_cpu_type.

* imx28: Fix issue with GCC 5.xMåns Rullgård2015-08-12-1/+1
| | | | | | | | | | | | | | The semantics for non-static functions declared inline have changed in gcc5, causing the empty functions not to be emitted as an external symbol. Since lowlevel_init() is only referenced from start.S, it should not be declared inline at all.

* cppcheck cleanup: fix nullPointer errorsWolfgang Denk2014-11-07-0/+2
| | | | | | | | | | | There are a number of places where U-Boot intentionally and legally accesses physical address 0x0000, for example when installing exception vectors on systems where these are located in low memory. Add "cppcheck-suppress nullPointer" comments to silence cppcheck where this is intentional and legal. Signed-off-by: Wolfgang Denk <wd@denx.de>

* arm: mxs: Fix vectoring table craftingMarek Vasut2013-06-03-3/+22
| | | | | | | | | | | | The vectoring table has to be placed at 0x0, but U-Boot on MX23/MX28 starts from RAM, so the vectoring table at 0x0 is not present. Craft code that will be placed at 0x0 and will redirect interrupt vectoring to proper location of the U-Boot in RAM.

* imx: Move some i.MX common functions into the imx-common directoryStefan Roese2013-04-22-63/+0
| | | | | | | | | | | | | | | | | | This patch moves the following functions into the imx-common directory: - mxs_wait_mask_set() - mxs_wait_mask_clr() - mxs_reset_block() These are currently used by i.MX28. But the upcoming GPMI NAND port for i.MX6 will also use these functions. So lets move them to a common location to re-use them.

* imx: Move some header files from arch-mxs to imx-commonStefan Roese2013-04-22-1/+1
| | | | | | | | | | | | | | | | | | | The following headers are moved to a i.MX common location: - regs-common.h - regs-apbh.h - regs-bch.h - regs-gpmi.h - dma.h This way this header can be re-used also by other i.MX platforms. For example the i.MX6 which will need it for the upcoming NAND support.
