- Addresses compiler error due to missing semicolon - Removes use of preprocessor macros with ANDROID_AB_BACKUP_OFFSET
Bug was found by noticing a semicolon was missing and not causing a compiler error when CONFIG_ANDROID_AB_BACKUP_OFFSET was set. I submitted a patch to fix the semicolon before fixing the #if's. Testing the latter patch without the former with ANDORID_AB_BACKUP_OFFSET set will cause a compiler error.
What's changed in V2? ---------------------
The second verison of changes removes the #if preprocessor macros to use C conditionals instead. There was some minor refactoring required to get this to work, so I did more thourough testing to ensure the backup data works as expected.
I also realized that CONFIG_VAL is not needed because there's no reason for the SPL or TPL to have different values for the backup address. I opted to just use CONFIG_ANDROID_AB_BACKUP_OFFSET directly.
How was this patch series tested? ---------------------------------
I built for my target with CONFIG_ANDROID_AB_BACKUP_OFFSET set to 0x1000. I first verified that the device can normally boot. I then ran dd before rebooting to corrupt the primary data. I confirmed that the backup was used to properly restore the primary. I then corrupted both the primary and backup data and confirmed that the primary and backup were both reinitialized to default values. Lastly, I corrupted the backup data and not the primary data and confirmed that the backup was restored the primary data.
