The current rsa_verify() requires five parameters for a RSA public key
for efficiency while RSA, in theory, requires only two. In addition,
those parameters are expected to come from FIT image.

purpose of implementing UEFI secure boot, in particular, image
authentication as well as variable authentication, where the essential
two parameters are set to be retrieved from one of X509 certificates in
signature database.

So, in this patch, additional three parameters will be calculated on the
fly when rsa_verify() is called without fdt which should contain
parameters above.

This calculation heavily relies on "big-number (or multi-precision)
library." Therefore some routines from BearSSL under MIT license are
imported in this implementation.

("[v6,0/7] rsa: extend rsa_verify() for UEFI secure boot").

Later on, Heinrich stressed the urgency of the issue in
https://patchwork.ozlabs.org/patch/1250858/#2379069:

 >>>>>>>>>
 We should finalize the topic as it stops EFI patches from being merged
 >>>>>>>>>

On the surface, the problem is caused by U-Boot commits [2-3], which
employed 'u32' in 'include/image.h', while historically U-Boot tooling
stayed agnostic on the {u,s}{8,16,32} types.

Thanks to Tom, Yamada-san and Heinrich, the following solutions have
been put head-to-head ('+' pros, '-' cons):

 A. Use an equivalent fixed-size type, i.e. s/u32/uint32_t/ in both
    android function prototypes (image.h) and definitions (c file):
    + quick and low-line-count
    - creates a 'soup' of fixed-sized types in the Android C file
    - will confuse contributors
    - is going against Linux kernel best practices [4]

 B. Guard Android functions by '!defined(USE_HOSTCC)' in image.h:
    + quick and low-line-count
    + reflects the reality (no android function is used by tooling)
    + zero impact on other subsystems
    - ifdeffery may look annoying (pre-existing problem of image.h)

 C. Make {u8,u16,u32} available in U-Boot tooling:
    + quick and low-line-count
    + [Yamada-san][5]:
      * forbidding u32 for tools is questionable to me
      * Linux kernel and Barebox use {u8,u16,u32} for the tools space
    - breaks U-Boot tradition?
    - has larger impact than [A] and [B]
    - adds type complexity/inconsistency in the tooling space

 D. [Yamada-san] Refactor the headers to minimize the code shared
    between U-Boot space and tooling space:
    + probably the long-term solution
    - high effort
    - can be seen/done as an incremental update on top of [B]

Looking at the above, [B] looks like the natural way to go forward.

domains during device removal. It hapens first when removing
gpio0 (gpio@5d080000) device, here its power domain device
'lsio_gpio0' is obtained for switching off power. Since the
obtained 'lsio_gpio0' device is removed afterwards, its power
domain is also switched off and here the parent power domain
device 'lsio_power_domain' is optained for switching off the
power. Thereafter, when the obtained 'lsio_power_domain' is
removed, device_remove() removes its first child 'lsio_gpio0'.
During this child removal the 'lsio_power_domain' device is
obtained again for switching and when removing it later,
the same child removal is repeated, so we are stuck in an
endless loop. Below is a snippet from dm tree on i.MX8QXP

mx7dsabresd: Boot in non secure by default

Booting a mainline kernel in secure mode on i.MX7D causes only
one CPU to be brought up.

Change it to booting in non secure mode by default, which

Before commit 83cfbeb0df9f ("net: phy: Fix mask so that we can identify

This introduces support for the NC-SI protocol, modelled as a phy driver
for other ethernet drivers to consume.

NC-SI (Network Controller Sideband Interface) is a protocol to manage a
sideband connection to a proper network interface, for example a BMC
(Baseboard Management Controller) sharing the NIC of the host system.
Probing and configuration occurs by communicating with the "remote" NIC
via NC-SI control frames (Ethernet header 0x88f8).

This implementation is roughly based on the upstream Linux
implementation[0], with a reduced feature set and an emphasis on getting
a link up as fast as possible rather than probing the full possible
topology of the bus.
The current phy model relies on the network being "up", sending NC-SI
command frames via net_send_packet() and receiving them from the
net_loop() loop (added in a following patch).

The ncsi-pkt.h header[1] is copied from the Linux kernel for consistent
field definitions.

imx8qxp_mek: Fix the console command line string

Currently the expansion of the console variable leads to
the following kernel command line:

console=ttyLP0,${baudrate} earlycon root=/dev/mmcblk1p2 rootwait rw

, which causes the console to not show characters after the LPUART driver
is probed as the 'baudrate' variable is not properly translated.

Fix it by splitting the console variable in two parts: one for the

serial: ns16550: Move PCI access from ofdata_to_platdata() to probe()

Currently the ofdata_to_platdata() method calls dev_read_addr_pci(),
which potentially accesses the parent PCI bus. If this happens before
the parent PCI bus is probed the resulting address will be wrong.

This behavior was triggered by commit 82de42fa1468 ("dm: core:
Allocate parent data separate from probing parent").

According to a comment in drivers/pci/pci-uclass.c [1] accessing
the PCI parent bus in ofdata_to_platdata() is not allowed, and the
access should be moved to the probe() function.

Move the call to dev_read_addr_pci() and the related handling of the
'addr' value from the ofdata_to_platdata() to its own function,
which is then called from the probe() method.

While moving the code, the comment /* try Processor Local Bus device
first */ was dropped. It was initially added with commit 3db886a5bf38
("serial: ns16550: Support ns16550 compatible pci uart devices") and
later made obsolete with commit 33c215af4b9d ("dm: pci: Add a function
to read a PCI BAR").

[1] Comment in drivers/pci/pci-uclass.c:
"A common cause of this problem is that this function is called in the
ofdata_to_platdata() method of @dev. Accessing the PCI bus in that
method is not allowed, since it has not yet been probed. To fix this,
move that access to the probe() method of @dev instead."
