MD Danish Anwar <danishanwar@ti.com> says:
Introduce ICSSG PRUETH support in uboot. The ICSSG driver is used in TI
AM654 SR2.0.
The ICSSG PRU Sub-system runs on EMAC firmware. This series Introduces
support for ICSSG driver in uboot.
This series has been tested on AM65x SR2.0, and the ICSSG interface is
able to ping / dhcp and boot kernel using tftp in uboot.
To use ICSSG2 ethernet, the ICSSG firmware needs to be loaded to PRU RPROC
cores and RPROC cores need to be booted with the firmware. This step is
done inside driver similar to kernel.
The remoteproc driver uses request_fw_into_buf() API from fs-loader driver
to load and start rproc with the required firmwares.
This series only introduces driver files. The device tree and config
changes to enable ICSSG driver will be introduced later.
|
|
This is the PRUSS Ethernet driver for TI AM654 SR2.0 and later SoCs with
the ICSSG PRU Sub-system running EMAC firmware. ICSSG Subsystem supports
two slices per instance. This driver caters to both slices / ports of
the icssg subsystem.
Since it is not possible for Ethernet driver to register more than one
port for a given instance, this patch introduces top level PRUETH as
UCLASS_MISC and binds UCLASS_ETH to individual ports in order to support
bringing up more than one Ethernet interface in U-Boot.
Since top level driver is UCLASS_MISC, board files would need to
instantiate the driver explicitly.

The function uniphier_mem_map_init() is to change global variable
'mem_map', which is referenced to get_page_table_size() to calculate
the size of page table.
However, uniphier_mem_map_init() is called after get_page_table_size(),
so the size of page table and 'mem_map' become inconsist each other.
After all, U-Boot fails to boot on chip with memory map different from
default map,
uniphier_mem_map_init() should be moved to dram_init(), which is
called before get_page_table_size().

During the boot, the EFI loader maps the memory from ram_top to ram_end

the following error message:

The maximum frequency of the A53 CPU on the AM62 depends on the speed
grade of the SoC. However, this value is hardcoded in the DT for all
AM62 variants, potentially causing specifications to be exceeded. Moreover,
setting a common lower frequency for all variants increases boot time.
To prevent these issues, modify the DT at runtime from the R5 core to
adjust the A53 CPU frequency based on its speed grade.

The implementation of map_range() creates the requested mapping by
walking the page tables, iterating over multiple PTEs and/or descending
into existing table mappings as needed. When doing so, it assumes any
pre-existing valid PTE to be a table mapping. This assumption is wrong
if the platform code attempts to successively map two overlapping ranges
where the latter intersects a block mapping created for the former.
As a result, map_range() treats the existing block mapping as a table
mapping and descends into it i.e. starts interpreting the
previously-mapped range as an array of PTEs, writing to them and
potentially even descending further (extra fun with MMIO ranges!).
Instead, pass any valid non-table mapping to split_block(), which
ensures that it actually was a block mapping (calls panic() otherwise)
before splitting it.

The USB VBUS supply for the type-A port is enabled via a GPIO regulator.
This is incorrectly modelled in Linux where only the PCIe dependency is
expressed. The correct way to handle this will be through a
usb-connector node, but for now we'll just mark the regulator as
always-on so that it will be enabled automatically during boot.

We don't support the RPM(h)PD power domains in U-Boot, and we don't need
to - the necessary resources are on, and we aren't going to enter any
low power modes.
We could try using a no-op device, but this requires adding a compatible
for every platform, and just pollutes the driver model. So instead let's
just remove every "power-domains" property that references the RPM(h)pd
power controller. This takes <1ms as we're using OF_LIVE.
Of note, this only applies to drivers which are loading post-relocation.
Drivers loaded pre-reloc that reference the rpm(h)pd still need
DM_FLAG_DEFAULT_PD_CTRL_OFF in their flags.

We don't support USB super-speed in U-Boot yet, we lack the SS PHY
drivers, however from my testing even with a PHY driver there seem to be
other issues when talking to super-speed peripherals.
In pursuit of maintaining upstream DT compatibility, and simplifying
porting for new devices, let's implement the DT fixups necessary to
configure USB in high-speed only mode at runtime. The pattern is
identical for all Qualcomm boards that use the Synaptics DWC3
controller:
* Add an additional property on the Qualcomm wrapper node
* Remove the super-speed phy phandle and phy-name entries.

There are cases when previous bootloader stage leaves some seemingly
valid value in r0, which in fact does not point to valid FDT
blob. This behavior was encountered when trying to boot U-Boot as
"hyp" loader on SA8155P-ADP.
To be sure that we really got the pointer to a device tree we need to
validate it with fdt_check_header() function.
Note: This approach is not 100% fool-proof, as get_prev_bl_fdt_addr()
theoretically can return a pointer to a region that is not physically
mapped and we will get data abort exception when fdt_check_header()
will try to access it. But at this early boot stage we don't know
where RAM is anyways so there is little we can do.
