|
|
* api/api_storage.c the type signature of lbaint_t will be different if
|
|
* CONFIG_SYS_64BIT_LBA is enabled for the board, which can result in various
|
|
* bugs.
|
|
* So simply define lbasize_t as an unsigned long, since this was what was done
|
|
* anyway for at least 13 years, but don't undefine CONFIG_SYS_64BIT_LBA.
