Hi Fabio,
It looks like we need one more fixup after commit c73368150 on the first run/older (non R, Dialog, bug wired extra Capacitor) version of this board.. Do you happen to have any in your lab?
U-Boot 2013.01-rc2-dirty (Dec 20 2012 - 15:55:01)
Board: MX53 LOCO I2C: ready DRAM: 1 GiB pmic_alloc: No available memory for allocation! pmic_init: POWER allocation error! CPU: Freescale i.MX53 family rev2.0 at 800 MHz Reset cause: POR MMC: FSL_SDHC: 0, FSL_SDHC: 1 *** Warning - bad CRC, using default environment
(and it just keeps on resetting)
It looks to be failing after calloc... http://git.denx.de/?p=u-boot.git;a=blob;f=drivers/power/power_core.c#l100
100 p = calloc(sizeof(*p), 1); 101 if (!p) { 102 printf("%s: No available memory for allocation!\n", __func__); 103 return NULL; 104 }
I can reproduce this issue using top of head U-boot tree.
It seems indeed to be caused by:

pmic: Extend PMIC framework to support multiple instances of PMIC devices
The PMIC framework has been extended to support multiple instances of the variety of devices responsible for power management. This change allows supporting of e.g. fuel gauge, charger, MUIC (Micro USB Interface Circuit). Power related includes have been moved to ./include/power directory. This is a first of a series of patches - in the future "pmic" will be replaced with "power".
Two important issues: 1. The PMIC needs to be initialized just after malloc is configured 2. It uses list to hold information about available PMIC devices

I am Ccing Lukasz/Stefano in case they have any suggestion.
With the new PMIC framework: is it safe to call the PMIC API from board_init function?
