Subject: [PATCH] hw/microblaze: pass random seed to fdt mainline inclusion
|
|
commit b91b6b5a2cd83a096116929dfc8e016091080adc category: bugfix
|
|
|
|
---------------------------------------------------------------
|
|
|
|
If the FDT contains /chosen/rng-seed, then the Linux RNG will use it to
|
|
initialize early. Set this using the usual guest random number
|
|
generation function. This FDT node is part of the DT specification.
