This patch series implements following smp related features.
Some of the work has been inspired from ARM64.
1. Decouple linux logical cpu ids from hardware cpu id
2. Support cpu hotplug.
Tested on QEMU & HighFive Unleashed board with/without SMP enabled.
v1->v2:
1. Dropped cpu_ops patch.
2.
This patch enable support for cpu hotplug in RISC-V.
In absence of generic cpu stop functions, WFI is used
to put the cpu in low power state during offline. An IPI
is sent to bring it out of WFI during online operation.
Tested both on QEMU and HighFive Unleashed board with
4 cpus. Test result

Firmware configures a certain number of MSIX vectors to each of
enabled RVU PF/VF. When a block LF is attached to a PF/VF, number
of MSIX vectors needed by that LF are set aside (out of PF/VF's
total MSIX vectors) and LF's msix_offset is configured in HW.

This patch adds basic template for Marvell OcteonTX2's

RVU AF driver will use APIs exported by this driver
for various things like PF to physical interface mapping,
loopback mode, interface stats etc.

From: Linu Cherian
Each of the enabled CGX LMAC is considered a physical
interface and RVU PFs are mapped to these. VFs of these
SRIOV PFs will be virtual interfaces and share CGX LMAC
along with PF.
This mapping info will be used later on for Rx/Tx pkt steering.

fork clears dirty/accessed bits from new ptes in the child. This logic
has existed since mapped page reclaim was done by scanning ptes when
it may have been quite important. Today with physical based pte

If we are being configured via pdata we don't necessarily have
any gpio mappings being configured that way so pdata->gpio_config
could be NULL.

The From and the first Signed-off-by lines should match, so use

When using DMA, if the DMA addr spans 128MB boundary, we have to split
the DMA transfer into two so that each one doesn't exceed the boundary.
patch1 adds adma_table_cnt to struct sdhci_host so that driver can
control the ADMA table count.
patch2 introduces adma_write_desc() hook to struct
The function tty_port_tty_get() gets a reference to the tty. Since
the code is not using tty_port_tty_set(), the reference is kept
even after closing the tty.
Avoid using tty_port_tty_get() by directly access the tty instance.
Since lpuart_start_rx_dma() is called from the .startup() and
