Restrictions on MSR instruction not implemented correctly in FVP for R52

[adamlewisWHIS]

On Windows 10, using FVP for R52 v11.27.19 While in Hyp mode, the instruction: MSR LR_usr, R1 (encoded as 0xE126F201 according to my memory view) should result in an Undef abort, because section F5.2.2 of ARM DDI 0487I.a claims that R8_usr-R12_usr, SP_hyp, LR_usr, and SPSR_hyp are all restricted while in Hyp mode. Instead, it is executed successfully.

Unsure if this is the right place to report the issue :)
