This extends the Firehose protocol implementation to support the VIP extension. It implements a state machine that counts the number of packets sent, then injects the VIP table as the next RAW packet when the Firehose programmer runs out of provided digests and needs a new table of digests to validate the next packets. For example: Packet 0: DigestsTableToSign.bin.mbn (53 digest + 1 digest of next table) Packet 1: <configure> Packet 2: <program> Packet 3: ... ... Packet 54: ChainedTableOfDigests0.bin (255 digests + digest of next table) Packet 55: <program> ... Packet 309: ChainedTableOfDigests1.bin To enable VIP extension provide a path where previously generated VIP tables are stored using "--vip-table-path" param: $ qdl --vip-table-path "<vip-table-path>" prog_firehose_ddr.elf \ rawprogram*.xml patch*.xml Signed-off-by: Igor Opaniuk <igor.opaniuk@oss.qualcomm.com>
