This depends on the specific features of your hardware.2s

Eventually you can increase the I2C clock.

Or use a h/w I2C driver instead of the soft-I2C driver.

Eventually you have plenty of memory that is available early (say,
several MB of L2 cache or so :-) and you can read the whole
environment into "RAM" in one rush.

Except for that there is little we can do. I2C is a PITA, also
reliability-wise.

Best regards,

Wolfgang Denk
