2015-10-23nios2: map physical address to uncached virtual addressThomas Chou
Add ioremap() to map physical address to uncached virtual address. We need this to convert the reg address from the device tree. The order of headers inclusion in interrupts.c is changed because common.h will include board header that contains IO_REGION_BASE. In the future, the IO_REGION_BASE should be decided from the device tree. tree Signed-off-by: Thomas Chou <thomas@wytron.com.tw> Acked-by: Marek Vasut <marex@denx.de> Reviewed-by: Simon Glass <sjg@chromium.org>
2015-10-23nios2: enable malloc() pool before relocationThomas Chou
Enable malloc() pool before relocation, because this is needed to use serial uclass. Signed-off-by: Thomas Chou <thomas@wytron.com.tw> Reviewed-by: Marek Vasut <marex@denx.de>
2015-10-23nios2: call board_init_f_memThomas Chou
We will need CONFIG_SYS_MALLOC_F_LEN to use serial uclass. So we shall undefine CONFIG_SYS_GENERIC_GLOBAL_DATA, and call board_init_f_mem() to allocates early malloc() memory with size of CONFIG_SYS_MALLOC_F_LEN in board_f.c.

Since commit 44c6e6591cb451ae606f8bde71dd5fb7b4002544 "rename _end to __bss_end__" , the _end was removed. But we need it now for separated device tree control, ie, CONFIG_OF_SEPARATE .

2015-10-23nios2: remove gp assignments in link scriptThomas Chou
Since we don't use gp for small data with option "-G0", we use gp as global data pointer. The _gp location is not needed. The ALIGN(16) was for gp only. It is removed, so that we can get correct address of dtb in u-boot-dtb.bin image.

2015-10-23nios2: enlarge the code relocation rangeThomas Chou
As we will use u-boot-dtb.bin, the code relocation range should be adjusted to accommodate the additional dtb. It might be overkilled to look into dtb header to find the dtb size, so we will simply use CONFIG_SYS_MONITOR_LEN. Signed-off-by: Thomas Chou <thomas@wytron.com.tw>
2015-10-23nios2: BSS should be cleared only after board_init_fThomas Chou
As dtb in u-boot-dtb.bin overlapped the BSS section, we should delay the clearing of BSS until dtb is relocated in board_init_f(). Signed-off-by: Thomas Chou <thomas@wytron.com.tw> Acked-by: Marek Vasut <marex@denx.de>

2015-10-22drivers: gpio: omap: add support for parsing additional gpio parametersMugunthan V N
With DM_GPIO, gpio parameters like ACTIVE_(LOW/HIGH) are to be parsed in xlate gpio drivers-ops. Since xlate is not implemented in omap_gpio driver, the driver considers all gpio to be ACTIVE_HIGH which is the default case and fails to return actual gpio status for ACTIVE_LOW gpios. So adding .xlate ops to omap_gpio. Signed-off-by: Mugunthan V N <mugunthanvnm@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com> Reviewed-by: Simon Glass <sjg@chromium.org>
