This series adds support for booting mx28 based boards which do not include a battery as per Freescale application note AN4199
Patch 2 (which implements booting without a battery) is based on a patch submitted to the Freescale community forums by Damien Gotfroi (Cc'd)
The patch series adds the following functionality (in oreder of implementation) - Debug output for mxs SPL (define DEBUG and CONFIG_SPL_SERIAL_SUPPORT in order to enable) - Ability to boot mx28 boards without a battery as per AN4199 (define CONFIG_SYS_MXS_VDD5V_ONLY to enable) - A tight loop (with 'Waiting for JTAG user') at the completion of SPL init if booting with the bootmode jumpers set to JTAG - Move the PLL power-up to a more logical location and properly initialise and check for PLL lock - Finally, add the G2C1 board
Graeme Russ (5): Add debug output to mx29 SPL source files Enable booting of mx28 without battery Add 'Wait for JTAG user' if booted in JTAG mode Move PLL power-up from power init to memory init Add support for ReachTech G2C1 board
