Re: [U-Boot] [U-Boot,v2] env: add spi_flash_read_env function

The spi_flash_read_env function is a wrapper over spi_flash_read, which enables the env to read multiple flash page size from flash until '\0\0' is read or the end of env partition is reached. Instead of reading the entire env size. When it reads '\0\0', it stops reading further the env and assumes that the rest of env is '\0'.

This is an optimization for large environments that contain few bytes environment variables. In this case it doesn't need to read the entire environment and only few pages.

Applied to u-boot/master, thanks!
