McciBootloaderBoard_CatenaAbz_SvcHandler()

static void McciBootloaderBoard_CatenaAbz_SvcHandler ( McciBootloaderPlatform_ARMv6M_SvcRq_t  svcRequest, McciBootloaderPlatform_ARMv6M_SvcError_t *  pErrorCode, uint32_t  arg1, uint32_t  arg2  )

SVC handler – provides very limited facilities to the application after boot.

• McciBootloaderPlatform_ARMv6M_SvcRq_GetUpdatePointer: gets the address used by this bootloader for the EEPROM update flag.
• McciBootloaderPlatform_ARMv6M_SvcRq_HashInit: initializes a hash calculation. arg1 points to a 64 byte buffer that is filled with the initial hash value.
• McciBootloaderPlatform_ARMv6M_SvcRq_HashBlocks: accumulates hash. arg1 points to McciBootloaderPlatform_ARMv6M_SvcRq_HashBlocks_Arg_t object.
• McciBootloaderPlatform_ARMv6M_SvcRq_HashFinish: finishes a hash calculation. arg1 points to McciBootloaderPlatform_ARMv6M_SvcRq_HashFinish_Arg_t.
• McciBootloaderPlatform_ARMv6M_SvcRq_Verify64: does a time-invariant comparison of two 64-byte buffers.

TODO(tmm@m.nosp@m.cci..nosp@m.com): this should be refactored because it's essentially portable. The board specific SVC handler should delegate to a portable common block of logic.
