kconfig / kbuild: re-sync with Linux 4.18
Align Kconfig and Kbuild logic to Linux 4.18 release with minimal impact
on files outside of this scope.
Our previous Kconfig sync was done by commit
e91610da7c8a ("kconfig:

A very small number of changes upstream since our sync with v4.17-rc4
that exist in the v4.18 release have already been applied here and have
been omitted from the list in this commit (and are readily available in

This issue prevents us from importing the upstream Linux commit

extend rsa_verify() for UEFI secure boot:
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.
So this function won't fit very well when we want to use it for the
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.

image.h: isolate android_image_* functions from tooling
On Feb. 16, 2020, Tom reported [1] build failure of U-Boot in-tree
tooling after applying https://patchwork.ozlabs.org/cover/
1229663/
("[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.

Currently when booting the kernel on i.MX8 U-Boot hangs in an
endless loop when switching off dma, connectivity or lsio power
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
for better illustration of the DM devices relationship:
Class Index Probed Driver Name
-----------------------------------------------------------
root 0 [ + ] root_driver root_driver
...
simple_bus 0 [ + ] generic_simple_bus |-- imx8qx-pm
power_doma 0 [ + ] imx8_power_domain | |-- lsio_power_domain
power_doma 1 [ + ] imx8_power_domain | | |-- lsio_gpio0
power_doma 2 [ + ] imx8_power_domain | | |-- lsio_gpio1
Do not remove a power domain device if it is a parent of the
currently controlled device.

Before commit

phy: Add support for the NC-SI protocol
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.

mmc: am654_sdhci: Implement workaround for card detect
The 4 bit MMC controllers have an internal debounce for the SDCD line
with a debounce delay of 1 second. Therefore, after clocks to the IP are
enabled, software has to wait for this time before it can power on the
controller.
Add a deferred_probe() callback which polls on sdcd for a maximum of 2 seconds
before switching on power to the controller or (in the case of no card)
returning a ENOMEDIUM. This pushes the 1 second wait time to when the
card is actually needed rather than at every probe() making sure that
users who don't insert an SD card in the slot don't have to wait such a
long time.

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."
