f79680184d Runtime key derivation with hardcoded key sources
* aes: add aes128EcbCrypt() as a one-shot function to perform AES-128-ECB crypto. The rest of the codebase now calls this function whenever suitable.

* fs_ext: add const keyword to IPC input structs wherever suitable.

* key_sources: add hardcoded master key vectors (prod, dev); master KEK sources (Erista, Mariko); master key source; ticket common key source; SMC key type sources; SMC seal key masks; AES key generation source; NCA header KEK source; NCA header key source and NCA KAEK sources. Also fixed the hardcoded gamecard CardInfo key source for dev units (it was previously generated using retail keydata, my bad).

* keys: remove keysGetNcaMainSignatureModulus(); remove keysDecryptNcaKeyAreaEntry(); repurpose keyset struct to only hold keys that can actually be used for the current hardware type; remove KeysGameCardKeyset; remove keysIsXXModulusYYMandatory() helpers; remove keysRetrieveKeysFromProgramMemory(); remove keysDeriveSealedNcaKeyAreaEncryptionKeys(); add keysDeriveMasterKeys() and keysDerivePerGenerationKeys(); rename keysDeriveGameCardKeys() -> keysDeriveGcCardInfoKey(); add small reimplementations of GenerateAesKek, LoadAesKey and GenerateAesKey; add keysLoadAesKeyFromAesKek() and keysGenerateAesKeyFromAesKek() wrappers. Furthermore, master key derivation is now carried out manually using hardcoded key sources and the last known master key, which is loaded from the Lockpick_RCM keys file -- if the last known master key is unavailable, the key derivation algorithm will then fallback to TSEC root key / Mariko KEK based key derivation, depending on the hardware type.

* nca: add hardcoded NCA man signature moduli (prod, dev); merge ncaDecryptKeyArea() and ncaEncryptKeyArea() into ncaKeyAreaCrypt().

* nxdt_utils: add utilsIsMarikoUnit(); remove _utilsAppletModeCheck(); rename utilsAppletModeCheck() -> utilsIsAppletMode().

* services: remove spl:mig dependency (yay).

* smc: add SmcKeyType enum; add SmcSealKey enum; add SmcGenerateAesKekOption struct; add smcPrepareGenerateAesKekOption().

5cc83491c1 Use verbosity-level-based log macros everywhere.
Also, Result codes are now just printed using %X.

c1e3dc719f More NCA changes.
* Made ncaGenerateEncryptedFsSectionBlock() entirely private. There's no point in keeping it public.

* Moved NCA FS section context initialization into its own function, ncaInitializeFsSectionContext().

* Hash data boundaries are now checked while initializing each NCA FS section context, using ncaFsSectionValidateHashDataBoundaries(). Both ncaValidateHierarchicalSha256Offsets() and ncaValidateHierarchicalIntegrityOffsets() have been removed.

* Improved hash region access detection in _ncaReadFsSection() by implementing ncaFsSectionCheckHashRegionAccess().

* ncaGetFsSectionHashTargetProperties() is now used in pfs.c, romfs.c and bktr.c to retrieve the properties from the target hash layer.

* Updated sanity checks in pfsInitializeContext(), romfsInitializeContext() and bktrInitializeContext().
