Allow passing the partition name to "part start" and "part size" commands, so we can avoid magic numbers in the environment.
Consider one real use-case: in include/environment/ti/boot.h we have commands like these:
setenv boot_part 9 part start mmc ${mmcdev} ${boot_part} boot_start part size mmc ${mmcdev} ${boot_part} boot_size mmc read ${loadaddr} ${boot_start} ${boot_size}Now suppose that we have changed the partition table and boot_part now is 10. We will need to fix commands above. And anyone who relies on these boot commands, will need to change them accordingly, too (this was an actual case in our lab while testing Linux boot on Android environment).
By providing the option to pass partition name instead, we fix mentioned issue, by eliminating the necessity to use magic numbers.
