H1 is a Google security chip present in recent Chromebooks, Pixel phones
and other devices. Cr50 is the name of the software that runs on H1 in
Chromebooks.
This chip is used to handle TPM-like functionality and also has quite a
few additional features.
Add a driver for this.

At present driver model supports the IRQ uclass but there is no way to
request a particular interrupt for a driver.
Add a mechanism, similar to clock and reset, to read the interrupts
required by a device from the device tree and to request those interrupts.
U-Boot itself does not have interrupt-driven handlers, so just provide a
means to read and clear an interrupt. This can be useful to handle
peripherals which must use an interrupt to determine when data is
available, for example.
Bring over the basic binding file as well, from Linux v5.4. Note that the
older binding is not supported in U-Boot; the newer 'special form' must be
used.
Add a simple test of the new functionality.

There can be different types of interrupt controllers in a system and some
drivers may need to distinguish between these. In general this can be
handled using the device tree by adding the interrupt information to
device nodes.
However on x86 devices we have interrupt controllers which are not tied
to any particular device and not really used in U-Boot. These still need
to be inited, so a convenient method is to give each controller a type
and allow a particular controller type to be probed.
Add support for this in sandbox along with a test.

So far we have avoided adding a clock driver for Intel devices. But the
Designware I2C driver needs a different clock (133MHz) on Intel devices
than on others (166MHz). Add a simple driver that provides this
information.
This driver can be expanded later as needed.

The watchdog timer value was never updated in the hardware by this
driver, so the watchdog triggered on some random stale value that
was left in the hardware. The TI SPRUH37C says, quote:
20.4.3.9 Modifying Timer Count/Load Values and Prescaler Setting
...
After a write access, the load register value and prescaler ratio
registers are updated immediately, but new values are considered
only after the next consecutive counter overflow or after a new
trigger command (the WDT_WTGR register).
This means at least one trigger must happen. The driver probably
depended on someone calling it's .reset() callback, however that
is not guaranteed e.g. if the WDT operates without servicing.
Add this missing trigger.

UniPhier SoC updates for v2020.04 (2nd)
Denali NAND driver changes:
- Set up more registers in denali-spl for SOCFPGA
- Make clocks optional
- Do not assert reset signals in the remove hook
- associate SPARE_AREA_SKIP_BYTES with DT compatible
- switch to UCLASS_MTD
UniPhier platform changes:

- specify loadaddr for "source" command

UCLASS_MTD is a better fit for NAND drivers.
Make NAND_DENALI_DT depend on DM_MTD, which is needed to compile
drivers/mtd/mtd-uclass.c
Also, make ARCH_UNIPHIER select DM_MTD because all the defconfig
of this platform enables NAND_DENALI_DT.

Currently, the denali NAND driver in U-Boot configures the
SPARE_AREA_SKIP_BYTES based on the CONFIG option.
Recently, Linux kernel merged a patch that associates the proper
value for this register with the DT compatible string.

When the reset signal is de-asserted, the HW-controlled bootstrap
starts running unless it is disabled in the SoC integration.
It issues some commands to detect a NAND chip, and sets up registers
automatically. Until this process finishes, software should avoid
any register access.
Without this delay function, some of UniPhier boards hangs up while
executing nand_scan_ident(). (denali_read_byte() is blocked)

The Denali NAND driver in mainline Linux currently cannot deassert the
reset. The upcoming Linux 5.6 will support the reset controlling, and
also set up SPARE_AREA_SKIP_BYTES correctly. So, the Denali driver in
the future kernel will work without relying on any bootloader or firmware.
However, we still need to take care of stable kernel versions for a while.
U-boot should not assert the reset of this controller.

Tested-by: Marek Vasut <marex@denx.de> # On SoCFPGA Arria V
|
|
On Altera SoCFPGA, upon either cold-boot or power-on reset, the
Denali NAND IP is initialized by the BootROM ; upon warm-reset,
the Denali NAND IP is NOT initialized by BootROM. In fact, upon
warm-reset, the SoCFPGA BootROM checks whether the SPL image in
on-chip RAM is valid and if so, completely skips re-loading the
SPL from the boot media.
This does sometimes lead to problems where the software left
the boot media in inconsistent state before warm-reset, and
because the BootROM does not reset the boot media, the boot
media is left in this inconsistent state, often until another
component attempts to access the boot media and fails with an
difficult to debug failure. To mitigate this problem, the SPL
on Altera SoCFPGA always resets all the IPs on the SoC early
on boot.
This results in a couple of register values, pre-programmed by
the BootROM, to be lost during this reset. To restore correct
operation of the IP on SoCFPGA, these values must be programmed
back into the controller by the driver. Note that on other SoCs
which do not use the HW-controlled bootstrap, more registers
may have to be programmed.
This also aligns the SPL behavior with the full Denali NAND
driver, which sets these values in denali_hw_init().

In the RK3399 DRAM driver, the function set_ds_odt() supports operating
in two different modes, selected by the ctl_phy_reg argument: when true,
the function reads and writes directly from the DRAM registers, accessed
through "chan->pctl->denali_*"; when false, the function reads and
writes from an array, accessed through "params->pctl_regs.denali_*",
which is written to DRAM registers at a later time.
However, phy_config_io(), which is called by set_ds_odt() to do a subset
of its register operations, operates directly on DRAM registers at all
times. This means that it reads incorrect values (and writes new values
prematurely) when ctl_phy_reg in set_ds_odt() is false. Fix this by
passing in the address of the registers to work with.
This prevents an "Invalid DRV value" error in the SPL debug log and
(presumably) results in a more correct end state. See the following logs
