* qe: move immap_qe.h from arch directory into common directoryZhao Qiang2014-07-221-1/+1
| | | | | | | | ls1021 is arm-core and supports qe too. Move immap_qe.h into common directory for both arm and powerpc. Signed-off-by: Zhao Qiang <B45475@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
* i2c, bootcount: add support for bootcounter on i2c devicesHeiko Schocher2014-02-202-0/+45
| | | | | | | add support for bootcounter on an i2c device. And add a README for all bootcounter options. Signed-off-by: Heiko Schocher <hs@denx.de>
* am33xx: Make SoC bootcount driver have its own symbolTom Rini2013-11-112-1/+5
| | | | | | | | | Some am33xx boards may not use the RTC block for bootcount (as it may not be wired up for the board) and use some other facility. So add another symbol for the bootcount driver for the IP block. Acked-by: Heiko Schocher <hs@denx.de> Signed-off-by: Tom Rini <trini@ti.com>
* bootcount: store bootcount var in environmentHeiko Schocher2013-11-112-0/+30
| | | | | | | | | | | | | | | | If no softreset save registers are found on the hardware "bootcount" is stored in the environment. To prevent a saveenv on all reboots, the environment variable "upgrade_available" is introduced. If "upgrade_available" is 0, "bootcount" is always 0 therefore no need to save the environment on u-boot boot, if "upgrade_available" is 1 "bootcount" is incremented in the environment and environment gets written on u-boot start. So the Userspace Applikation must set the "upgrade_available" and "bootcount" variable to 0 (for example with fw_setenv), if a boot was successfully. Signed-off-by: Heiko Schocher <hs@denx.de>

Resolution consists in adjusting the list of object files in the main branch version. This also applies to two files which are not listed as conflicting but had to be modified: board/compulab/common/Makefile board/udoo/Makefile include/configs/omap4_common.h conflicts are due to the OMAP4 conversion to ti_armv7_common.h on the ARM side, and CONFIG_SYS_HZ removal on the main side. Resolution is to convert as this icludes removal of CONFIG_SYS_HZ. include/configs/pdnb3.h is due to a removal on ARM side. Trivial resolution is to remove the file. Note: 'git show' will also list two files just because they are new: include/configs/am335x_igep0033.h include/configs/omap3_igep00x0.h
| * TI:am33xx: Add bootcount support to ti_am335x_common.hTom Rini2013-11-011-0/+1
| | | | | | | | | | | | | | Enable the bootcount driver for am335x in general. We leave adding a bootlimit and altbootcmd to the environment to the board ports. Signed-off-by: Tom Rini <trini@ti.com>
| * bootcount_davinci: Switch to scratch register #2Tom Rini2013-11-011-4/+6
| | | | | | | | | | | | | | | | The RTC IP block here provides 3 scratch registers. Currently when using DeepSleep on am335x the scratch0/1 registers are used so moving ourself to scratch2 makes cooperation easier. Signed-off-by: Tom Rini <trini@ti.com>

* Consolidate bootcount code into drivers/bootcountStefan Roese2012-09-016-0/+343
This patch moves all bootcount implementations into a common directory: drivers/bootcount. The generic bootcount driver is now usable not only by powerpc platforms, but others as well.
