2015-05-26imx6: move all standard includes to mx6_common.hPeter Robinson
The linux/sizes.h, asm/arch/imx-regs.h, asm/imx-common/gpio.h, config_cmd_default.h includes are used fairly universally across imx6 boards so include them in mx6_common.h by default. We define CONFIG_SYS_NO_FLASH before config_cmd_default.h so that we don't have to undef CONFIG_CMD_FLASH / CONFIG_CMD_IMLS everywhere. Signed-off-by: Peter Robinson <pbrobinson@gmail.com>

91199f4a5a21a7cf9dd9e7c05e295a042f8c2b7e broke mmc based Falcon mode. The block_read function returns the number of blocks read thus the error check needs to look for a return of 0 blocks read.

2015-05-26thermal: imx_thermal: increase critical temperature thresholdTim Harvey
The CPU temperature grade from OTP is now used to define the critical threshold at which point we busyloop until we are below, however this threshold is still too low. Instead of 20C below the max CPU temperature, change it to 5C defined now by TEMPERATURE_HOT_DETLA for clarity. Rename 'passive' to 'critical' as that better defines our use case here. Additionally change the output of the busyloop message to show the max CPU temperature as well as current. Before: CPU Temperature is 101 C, too hot to boot, waiting... CPU Temperature is 101 C, too hot to boot, waiting... After: CPU Temperature (101C) too close to max (105C) waiting... CPU Temperature (101C) too close to max (105C) waiting...
