According to De Morgan's Law[1]: !(A && B) = !A || !B !(A || B) = !A && !B There are 5 places in the code where we find: #if !(defined(CONFIG_SYS_ICACHE_OFF) && defined(CONFIG_SYS_DCACHE_OFF)) and 4 places in the code where we find: #if (!defined(CONFIG_SYS_ICACHE_OFF) || !defined(CONFIG_SYS_DCACHE_OFF)) In words, the construct: !defined(CONFIG_SYS_[DI]CACHE_OFF) means: "is the [DI]CACHE on?" and the construct: defined(CONFIG_SYS_[DI]CACHE_OFF) means: "is the [DI]CACHE off?" Therefore !(defined(CONFIG_SYS_ICACHE_OFF) && defined(CONFIG_SYS_DCACHE_OFF)) means: "the opposite of 'are they both off?'" in other words: "are either or both on?" and: (!defined(CONFIG_SYS_ICACHE_OFF) || !defined(CONFIG_SYS_DCACHE_OFF) means: "are either or both on?" As a result, I've converted the 4 instances of '(!A || !B)' to '!(A && B)' for consistency. [1] https://en.wikipedia.org/wiki/De_Morgan%27s_laws Signed-off-by: Trevor Woerner <trevor@toganlabs.com> |
