[edk2-devel] [PATCH] UefiPayloadPkg/BootManager: Add PS2 keyboard support

[Ma, Maurice]

Hi, Guo,

Since PS2 keyboard is not commonly seen anymore,   do you think it is better to define a control variable in DSC so that the PS2 driver can be easily added or removed using build command line ?

Thanks
Maurice
