8 years agospl: Lightweight UBI and UBI fastmap support
Thomas Gleixner [Tue, 12 Jul 2016 18:28:12 +0000 (20:28 +0200)]
spl: Lightweight UBI and UBI fastmap support

Booting a payload out of NAND FLASH from the SPL is a crux today, as
it requires hard partioned FLASH. Not a brilliant idea with the
reliability of todays NAND FLASH chips.

The upstream UBI + UBI fastmap implementation which is about to
brought to u-boot is too heavy weight for SPLs as it provides way more
functionality than needed for a SPL and does not even fit into the
restricted SPL areas which are loaded from the SoC boot ROM.

So this provides a fast and lightweight implementation of UBI scanning
and UBI fastmap attach. The scan and logical to physical block mapping
code is developed from scratch, while the fastmap implementation is
lifted from the linux kernel source and stripped down to fit the SPL
needs.

The text foot print on the board which I used for development is:

6854 0 0 6854 1abd
drivers/mtd/ubispl/built-in.o

Attaching a NAND chip with 4096 physical eraseblocks (4 blocks are
reserved for the SPL) takes:

In full scan mode:      1172ms
In fastmap mode:          95ms

The code requires quite some storage. The largest and unknown part of
it is the number of fastmap blocks to read. Therefor the data
structure is not put into the BSS. The code requires a pointer to free
memory handed in which is initialized by the UBI attach code itself.

See doc/README.ubispl for further information on how to use it.

This shares the ubi-media.h and crc32 implementation of drivers/mtd/ubi
There is no way to share the fastmap code, as UBISPL only utilizes the
slightly modified functions ubi_attach_fastmap() and ubi_scan_fastmap()
from the original kernel ubi fastmap implementation.

powerpc/mpc85xx: T104x: Add nand secure boot target

For mpc85xx SoCs, the core begins execution from address 0xFFFFFFFC.
In non-secure boot scenario from NAND, this address will map to CPC
configured as SRAM. But in case of secure boot, this default address
always maps to IBR (Internal Boot ROM).
The IBR code requires that the bootloader(U-boot) must lie in 0 to 3.5G
address space i.e. 0x0 - 0xDFFFFFFF.

For secure boot target from NAND, the text base for SPL is kept same as
non-secure boot target i.e. 0xFFFx_xxxx but the SPL U-boot binary will
be copied to CPC configured as SRAM with address in 0-3.5G(0xBFFC_0000)
As a the virtual and physical address of CPC would be different. The
virtual address 0xFFFx_xxxx needs to be mapped to physical address
0xBFFx_xxxx.

Create a new PBI file to configure CPC as SRAM with address 0xBFFC0000
and update DCFG SCRTACH1 register with location of Header required for
secure boot.

While P3041 has a 1MB CPC and does not require SPL. On T104x, CPC
is only 256K and thus SPL framework is used.
The changes are only applicable for SPL U-Boot running out of CPC SRAM

ARM: tegra: pick up actual memory size

On Tegra186, U-Boot is booted by the binary firmware as if it were a
Linux kernel. Consequently, a DTB is passed to U-Boot. Cache the address
of that DTB, and parse the /memory/reg property to determine the actual
RAM regions that U-Boot and subsequent EL2/EL1 SW may actually use.

Given the binary FW passes a DTB to U-Boot, I anticipate the suggestion
that U-Boot use that DTB as its control DTB. I don't believe that would
work well, so I do not plan to put any effort into this. By default the
FW-supplied DTB is the L4T kernel's DTB, which uses non-upstreamed DT
bindings. U-Boot aims to use only upstreamed DT bindings, or as close as
it can get. Replacing this DTB with a DTB using upstream bindings is
physically quite easy; simply replace the content of one of the GPT
partitions on the eMMC. However, the binary FW at least partially relies
on the existence/content of some nodes in the DTB, and that requires the
DTB to be written according to downstream bindings. Equally, if U-Boot
continues to use appended DTBs built from its own source tree, as it does
for all other Tegra platforms, development and deployment is much easier.

Prior to that commit, there existed a gap between IH_ARCH_M68K and
IH_ARCH_MICROBLAZE, like follows.

  #define IH_ARCH_SPARC64         11      /* Sparc 64 Bit */

  #define IH_ARCH_NIOS2           15      /* Nios-II      */

The enum conversion broke the compatibility with existing uImage
files.  Reverting 555f45d8f916 will cause build error unfortunately,
so here is a more easy fix.

I dug the git history and figured out the gap was introduced by
commit 1117cbf2adac ("nios: remove nios-32 arch").  So, I revived
IH_ARCH_NIOS just for filling the gap.

I added comments to each enum block.  Once we assign a value to
IH_... it is not allowed to change it.
