2009-06-04Redundant Environment: protect full sector sizeWolfgang Denk
Several boards used different ways to specify the size of the protected area when enabling flash write protection for the sectors holding the environment variables: some used CONFIG_ENV_SIZE and CONFIG_ENV_SIZE_REDUND, some used CONFIG_ENV_SECT_SIZE, and some even a mix of both for the "normal" and the "redundant" areas. Normally, this makes no difference at all. However, things are different when you have to deal with boards that can come with different types of flash chips, which may have different sector sizes. Here we may have to chose CONFIG_ENV_SECT_SIZE such that it fits the biggest sector size, which may include several sectors on boards using the smaller sector flash types. In such a case, using CONFIG_ENV_SIZE or CONFIG_ENV_SIZE_REDUND to enable the protection may lead to the case that only the first of these sectors get protected, while the following ones aren't. This is no real problem, but it can be confusing for the user - especially on boards that use CONFIG_ENV_SECT_SIZE to protect the "normal" areas, while using CONFIG_ENV_SIZE_REDUND for the "redundant" area. To avoid such inconsistencies, I changed all sucn boards that I found to consistently use CONFIG_ENV_SECT_SIZE for protection. This should not cause any functional changes to the code.
