i.MX6UL: Adding bootcount support

[Fabio Estevam]

Hi,

I'm trying to enable bootcount support on the imx6ul-evk board like this:

--- a/configs/mx6ul_14x14_evk_defconfig
+++ b/configs/mx6ul_14x14_evk_defconfig
@@ -110,3 +110,8 @@ CONFIG_SPLASH_SCREEN=y
 CONFIG_SPLASH_SCREEN_ALIGN=y
 CONFIG_BMP_16BPP=y
 CONFIG_IMX_WATCHDOG=y
+CONFIG_SYS_BOOTCOUNT_ADDR=0x020B0068
+CONFIG_SYS_BOOTCOUNT_SINGLEWORD=y
+CONFIG_BOOTCOUNT_LIMIT=y
+CONFIG_SYS_BOOTCOUNT_MAGIC=0xB0C4000
+CONFIG_SYS_BOOTCOUNT_BE=y

However, the 'bootcount' variable does not increment after a 'reset' command:

=> print bootcount
bootcount=1

Has anyone managed to get bootcount working on it?MX6UL?

Thanks,

Fabio Estevam
