PS1, Line 169: 	const uint8_t bits = 8;
> missing the line: […]

Oh, I can explain why this line is not here. At this patch, max_kernel_buf_size is still a global state (together with fd), they are defined in lines 47, 49. I am not removing global state in this patch, so I left it as is, and since max_kernel_buf_size is global I don't need to define it locally in init function.

I do remove global state later in https://review.coreboot.org/c/flashrom/+/52285 , but not here.

What do you think about it? I was trying to keep the purpose for each patch very focused.
