[U-Boot] CONFIG_ARM_ERRATA_7XXXX question again

[TigerLiu at viatech.com.cn]

Hi, experts:
I found some macro definitions, such as:
#define CONFIG_ARM_ERRATA_743622
#define CONFIG_ARM_ERRATA_751472

So, my question is:
Where do i get these errata descriptions?
Are there related to specific ARM SOC Vendors? Or just ARM Core's common
errata?

Best wishes,
