Subject: [PATCH v3 1/2] firmware: dmi: Add macro SMBIOS_ENTRY_POINT_SCAN_START
Date: Wed, 5 Feb 2020 12:08:32 +0800 [thread overview]
Message-ID: <1580875713-18252-1-git-send-email-yangtiezhu@loongson.cn> (raw)
Use SMBIOS_ENTRY_POINT_SCAN_START instead of 0xF0000, because other
archtecture maybe use a special start address such as 0xFFFE000 for
Loongson platform.

v3:
- split the v2 patch into two patches
- make MIPS DMI config depend on MACH_LOONGSON64
v2:
- add SMBIOS_ENTRY_POINT_SCAN_START suggested by Jean
- refine definitions and Kconfig by Jiaxun
