Subject: [PATCH 3/6] MIPS: BCM63XX: recognize Cable Modem firmware format
|
|
|
|
Add the firmware header format which is used by Broadcom Cable Modem
|
|
SoCs such as the BCM3368 SoC. We export the bcm_hcs firmware format
|
|
structure because it is used by user-land tools to create firmware
|
|
images for these SoCs and will later be used by a corresponding MTD
|
|
parser.
