Subject: [PATCH 1/1] env: Exit tools when invalid CRC found

fw_setenv and fw_printenv currently print a warning and use a default
environment compiled into the binary when an invalid CRC is found. This
modifies the default behavior to print an error and exit. This is
especially important when calling the tools from a script since the 
script depends on the exit code of the tool to know something went

Selecting CONFIG_SYS_I2C_ZYNQ and CONFIG_ZYNQ_I2C0 builds successfully (see Xilinx documentation). But those are old config options and should be replaced with CONFIG_I2C_CADENCE.

Selecting CONFIG_ENV_IS_IN_EEPROM causes the following assertion to fail:

cmd/eeprom.c:58:2: error: #error CONFIG_SYS_I2C_EEPROM_ADDR_LEN must be 1 or 2
 #error CONFIG_SYS_I2C_EEPROM_ADDR_LEN must be 1 or 2

I keep running into the following issue:

Jan 23 15:48:52 localhost irssi-notify.bash[23391]: ssh_askpass: exec(/usr/libexec/openssh/ssh-askpass): No such file or directory
Jan 23 15:48:52 localhost irssi-notify.bash[23391]: user@host: Permission denied (publickey).

After I installed openssh-askpass I get prompted for the password for my key every time ssh is called in the script.
