2021-01-27habanalabs/gaudi: unmask HBM interrupts after handlingOded Gabbay
As the driver does with all interrupts, we need to tell F/W to unmask the HBM interrupts after the driver handled them. Signed-off-by: Oded Gabbay <ogabbay@kernel.org>

Axe 'hl_pci_set_dma_mask()' and replace it with an equivalent 'dma_set_mask_and_coherent()' call. This makes the code a bit less verbose.

In case MMU is enabled, we must take MMU page size into consideration when reporting dram size to the user. This is because the MMU page size can be a value which is NOT a power-of-2 value.

DRAM physical page sizes depend of the amount of HBMs available in the device. this number is device-dependent and may also be subject to binning when one or more of the DRAM controllers are found to to be faulty.

2021-01-27bus: fsl-mc: add fsl-mc userspace supportIoana Ciornei
Adding userspace support for the MC (Management Complex) means exporting an ioctl capable device file representing the root resource container. This new functionality in the fsl-mc bus driver intends to provide userspace applications an interface to interact with the MC firmware. Commands that are composed in userspace are sent to the MC firmware through the FSL_MC_SEND_MC_COMMAND ioctl. By default the implicit MC I/O portal is used for this operation, but if the implicit one is busy, a dynamic portal is allocated and then freed upon execution. The command received through the ioctl interface is checked against a known whitelist of accepted MC commands. Commands that attempt a change in hardware configuration will need CAP_NET_ADMIN, while commands used in debugging do not need it.
