If you're going to add something new, a command is much more pleasant than env vars -- particularly if you stick to something like the familiar interfaces ("pix altbank", "qix altbank", etc), and include reporting of which bank was booted from if it's not there already. Of course, a fully standardized interface would be even better.
I'm assuming this hardware isn't at all compatible with pixis/qixis?

Yes, a fully standardized generic interface supporting all similar platforms with multiple banks would be better. What this patch currently does can be done with simple env vars, like :
setenv boot_bank_1 'i2c mw 0x24 0x7 0xfc; i2c mw 0x24 0x3 0xf5' setenv boot_bank_2 'i2c mw 0x24 0x7 0xfc; i2c mw 0x24 0x3 0xf4'

Calvin,
Do you want to stay with env, or still want this patch, or standardize the command?

Calvin,

Ideally, a fully standardized generic command interface supporting all similar platforms with multiple banks as well as other boot sources such as NAND and MMC, is the best option.
This patch looks good as an interim solution.

Thanks Scott for reviewing this patch

LS1012A has only one boot source i.e. QSPI
would be better. What this patch currently does can be done with simple env vars, like :
setenv boot_bank_1 'i2c mw 0x24 0x7 0xfc; i2c mw 0x24 0x3 0xf5' setenv boot_bank_2 'i2c mw 0x24 0x7 0xfc; i2c mw 0x24 0x3 0xf4'
...if the user knows to env reset those variables after the update (versus something that shows up in help), and if they don't get corrupted in a multi- user board farm environment, etc.
With env there is always a probability of getting erased. In that case user will not have these commands.
Better approach should be command which is always available. If required we can update the doc.

I meant that if there is any effort to standardize the command it should support multiple boot sources, not just bank selection.
