5 years agoAdd support for the NXP LS1021A-TSN board
Jianchao Wang [Thu, 18 Jul 2019 21:30:01 +0000 (00:30 +0300)]
Add support for the NXP LS1021A-TSN board

The LS1021A-TSN is a development board built by VVDN/Argonboards in
partnership with NXP.

It features the LS1021A SoC and the first-generation SJA1105T Ethernet
switch for prototyping implementations of a subset of IEEE 802.1 TSN
standards.

Supported boot media: microSD card (via SPL), QSPI flash.

Rev. A of the board uses a Spansion S25FL512S_256K serial flash, which
is 64 MB in size and has an erase sector size of 256KB (therefore,
flashing the RCW would erase part of U-Boot).

Rev. B and C of the board use a Spansion S25FL256S1 serial flash, which
is only 32 MB in size but has an erase sector size of 64KB (therefore
the RCW image can be flashed without erasing U-Boot).

To avoid the problems above, the U-Boot base address has been selected
at 0x100000 (the start of the 5th 256KB erase sector), which works for
all board revisions. Actually 0x40000 would have been enough, but
0x100000 is common for all Layerscape devices.

eTSEC3 is connecting directly to SJA1105 via an RGMII fixed-link, but
SJA1105 is currently not supported by uboot. Therefore, eTSEC3 is
disabled.

In the case of the tsec network driver, so far there has been no
mainline user of DM_ETH where the DT bindings get used.

In the case of the mdio bus, it looks like the "fsl,tsec-mdio" string
was made up for the documentation, but there is no mainline code that
parses the "compatible" property anyway.

In both cases, there are no DT blobs that contain the old strings.

So change the documentation to "fsl,etsec2" for the Ethernet ports and
"fsl,etsec2-mdio" for the MDIO buses, which are strings that Linux also
uses, at least for LS1021A.  More compatible strings can be added once
other (PowerPC) SoCs are migrated to DM_ETH.

The current ls1021a.dtsi doesn't match what was documented for the MDIO
buses anyway (the "compatible" is "gianfar" currently). This will be
fixed in the next patch.

distro_bootcmd: refactor virtio to support PCI block devices

Starting libvirt v5.3.0 with QEMU 4.0.0 use of PCI is automatic
and thus storage is connected via PCI, which is not visible to
U-Boot out-of-the-box.

Refactor to do "pci enum" followed by "virtio scan" to see PCI
connected storage, and allow bootloader to load kernel and
initramfs images.

Tested with Fedora/RISCV using releases: libvirt 5.4.0 & 5.5.0,
QEMU 4.0.0 and U-Boot 2019.07 RC4.

Add support for A/B boot process on AM57xx based boards:

  2. Extend 'emmc_android_boot' boot command (add commands for A/B boot
     process)

'ab_select' command is used to decide which slot should be used for
booting up. A/B metadata resides in 'misc' partition.

To activate the A/B boot process, the following config options must be
set:

    CONFIG_ANDROID_AB=y
    CONFIG_CMD_AB_SELECT=y

For successful A/B boot, the corresponding A/B infrastructure must be
involved on Android side [1] (including mounting system as root), and
disk must be partitioned accordingly.

When A/B boot is enabled, there are some known limitations currently
exist (not related to A/B patches, need to be implemented later):

  1. The 'Verified Boot' sequence is not supported
  2. dev path to system partition (system_a or system_b) is passed via
     'bootargs' as 'root=' argument like 'root=/dev/mmcblk1p12', but
     further we'll need to rework it with respect to dm-verity
     requirements [2]

In case when A/B partitions are not present in system (and A/B boot is
enabled), boot up process will be terminated and next message will be
shown:

    "boot_a(b) partition not found"

cmd: bcb: Use strcmp() instead of strncmp() for string literals

Quote from https://patchwork.ozlabs.org/patch/1104244/#2210814:

 ----------8<-----------
strncmp() is chosen for the sake of paranoid/defensive programming.
Indeed, strncmp() is not really needed when comparing a variable
with a string literal. We expect strcmp() to behave safely even if the
string variable is not NUL-terminated.

In the same scenario, Linux v5.2-rc7 uses both strcmp() and strncmp(),
but the frequency of strcmp() is higher:

$ git --version
git version 2.22.0
$ (Linux 5.2-rc7) git grep -En 'strncmp\([^"]*"[[:alnum:]]+"' | wc -l
1066
$ (Linux 5.2-rc7) git grep -En 'strcmp\([^"]*"[[:alnum:]]+"' | wc -l
1968

A quick "strcmp vs strncmp" object size test shows that strcmp()
generates smaller memory footprint (gcc-8, x86_64):

$ (U-Boot) size cmd/bcb-strncmp.o cmd/bcb-strcmp.o
   text    data     bss     dec     hex filename
   3373     400    2048    5821    16bd cmd/bcb-strncmp.o
   3314     400    2048    5762    1682 cmd/bcb-strcmp.o

So, overall, I agree to use strcmp() whenever variables are compared
with string literals.

image: android: allow to wrap uImage into the Android boot image

This allows to use any available compression format with Android boot image

Since not all available compression formats have a magic number we should
explicitly specify type of compression.

For this purpose using uImage format becomes very useful, as this format is
well-known by the community and mkimage tool is already available.

Usage example:
mkimage -A ARM64 -T kernel -C lzma -d Image.lzma out/kernel

At this moment only -C option is handled, but specifying -A and -T options
are recommended for compatibility reasons in the future.

Kernel that compressed with LZ4 can be already used without wrapping into
the uImage, but I recommend wrapping it into the uImage in order to avoid
situations when by some mistake legacy LZ4 is used, that is interpreted as
raw Image and causes CPU to enter Exception Handler without providing any
