Subject: [PATCH] Initialise rpi-firmware before clk-bcm2835
|
|
|
|
The IMA (Integrity Measurement Architecture) looks for a TPM (Trusted
|
|
Platform Module) having been registered when it initialises; otherwise
|
|
it assumes there is no TPM. It has been observed on BCM2835 that IMA
|
|
is initialised before TPM, and that initialising the BCM2835 clock
|
|
driver before the firmware driver has the effect of reversing this
|
|
order.
|
|
|
|
Change the firmware driver to initialise at core_initcall, delaying the
|
|
BCM2835 clock driver to postcore_initcall.
|
|
|
