Pali Rohár 5a91c439cb fix(plat/marvell/a3720/uart): fix UART parent clock rate determination
The UART code for the A3K platform assumes that UART parent clock rate
is always 25 MHz. This is incorrect, because the xtal clock can also run
at 40 MHz (this is board specific).

The frequency of the xtal clock is determined by a value on a strapping
pin during SOC reset. The code to determine this frequency is already in
A3K's comphy driver.

Move the get_ref_clk() function from the comphy driver to a separate
file and use it for UART parent clock rate determination.

Pali Rohár b9185c75f7 fix(plat/marvell/a3720/uart): fix configuring UART clock
When configuring the UART_BAUD_REG register, the function
console_a3700_core_init() currently only changes the baud divisor field,
leaving other fields to their previous value.

This is incorrect, because the baud divisor is computed with the
assumption that the parent clock rate is 25 MHz, and since the other
fields in this register configure the parent clock, which could have
been changed by U-Boot or Linux.

Fix this function to also configure the other fields so that the UART
parent clock is selected to be the xtal clock.

For example without this change TF-A prints only

    ERROR: a3700_system_off needs to be implemented

followed by garbage after plat_crash_console_init() is called.

After applying this change instead of garbage it also print crash info:

Pali Rohár 66a7752834 fix(plat/marvell/a3720/uart): fix UART clock rate value and divisor calculation
UART parent clock is by default the platform's xtal clock, which is
25 MHz.

The value defined in the driver, though, is 25.8048 MHz. This is a hack
for the suboptimal divisor calculation
  Divisor = UART clock / (16 * baudrate)
which does not use rounding division, resulting in a suboptimal value
for divisor if the correct parent clock rate was used.

Change the code for divisor calculation to
  Divisor = Round(UART clock / (16 * baudrate))
and change the parent clock rate value to 25 MHz.

The final UART divisor for default baudrate 115200 is not affected by
this change.

(Note that the parent clock rate should not be defined via a macro,
since the xtal clock can also be 40 MHz. This is outside of the scope of
this fix, though.)

Manish V Badarkhe a2a5a94569 fix(driver/auth): avoid NV counter upgrade without certificate validation
Platform NV counter get updated (if cert NV counter > plat NV counter)
before authenticating the certificate if the platform specifies NV
counter method before signature authentication in its CoT, and this
provides an opportunity for a tempered certificate to upgrade the
platform NV counter. This is theoretical issue, as in practice none
of the standard CoT (TBBR, dualroot) or upstream platforms ones (NXP)
exercised this issue.

To fix this issue, modified the auth_nvctr method to do only NV
counter check, and flags if the NV counter upgrade is needed or not.
Then ensured that the platform NV counter gets upgraded with the NV
counter value from the certificate only after that certificate gets
authenticated.

This change is verified manually by modifying the CoT that specifies
certificate with:
1. NV counter authentication before signature authentication
   method
2. NV counter authentication method only

Yann Gautier 70eb88b7d9 Revert "mmc:prevent accessing to the released space in case of wrong usage"
This reverts commit 13f3c5166f.
The STM32MP1 platform can no more boot qwith this change.
The driver will not be aware when the static struct in framework is updated.

Pali Rohár 40d08192aa drivers: marvell: comphy-a3700: Set TXDCLK_2X_SEL bit during PCIe initialization
Marvell Armada 3700 Functional Specifications, section 52.2 PCIe Link
Initialization says that TXDCLK_2X_SEL bit needs to be enabled for PCIe
Root Complex mode. Both U-Boot and Linux kernel support only Root Complex
mode. Set this bit.

Pali Rohár ccec1bd5ca drivers: marvell: comphy-a3700: Set mask parameter for every reg_set call
The third argument of the reg_set() function has name 'mask', which
indicates that it is a mask applied to the register value which is
going to be updated. But the implementation of this function uses
this argument to clear prior value of the register, i.e. instead of
  new_val = (old_val & ~mask) | (data & mask);
it does
  new_val = (new_val & ~mask) | data;

(The more proper name for this function should be reg_clrsetbits(),
 since internally it calls mmio_clrsetbits_32().)

To make code more readable set 'mask' argument to real mask, i.e. bits
of register values which are going to be updated.

This patch does not make any functional change, only cosmetic, due to
how 'mask' is interpreted.

Pali Rohár ee4c70ebb9 drivers: marvell: comphy-a3700: Fix configuring polarity invert bits
TXD_INVERT_BIT or RXD_INVERT_BIT needs to be set only in case when
appropriate polarity is inverted. Otherwise these bits should be
cleared.
