In my testing, Win7 Bitlocker fails to initialize if TPM memory region is
reported as ReadOnly.

Baranee:
The sample in TCG PC Client Platform Firmware spec describes this memory
range ReadWrite
Device (TPM) {
Name (_HID, EISAID("MSFT0101"))
Name (_CRS, ResourceTemplate() {
Memory32Fixed (ReadWrite, 0xFED40000, 0x5000,)
IRQ(Level, ActiveLow, Shared) {3,5,7,9,10,11,13,15}
})
}
I don't know the history why TPM.asl describes it ReadOnly. Do you meet any
problem with this setting?
Thanks & Best regards
Chao Zhang

SecurityPkg Maintainers,
Is there a specific reason to report TPM region 0xfed40000 as ReadOnly instead
of ReadWrite in ASL code? Thanks.
