On specific devices, read can return less bytes than expected. I noticed this problem on a EEPROM chip with 16Kbyte of memory. Defining an environment with more than 4Kbyte leads to less bytes read than expected and failures from fw_printenv/fw_setenv. This patch target to handle this issue by doing multiple reads instead of exiting directly.
