From e61b41517d2a91080f6416fdfb46efab9e5a55b4 Mon Sep 17 00:00:00 2001 From: Usama Arif Date: Tue, 11 Aug 2020 15:46:03 +0100 Subject: [PATCH] avb: Make AVB independent of fastboot AVB only uses CONFIG_FASTBOOT_BUF_ADDR from fastboot for memory. This memory is used for assigning temporary buffers. This can be assigned a new variable and used as CONFIG_AVB_BUF_ADDR. This is to support future boards that support AVB but dont support USB and therefore dont support FASTBOOT.
