x86: quark: Configure MTRR to enable cache

Quark SoC does not support MSR MTRRs. Fixed and variable range MTRRs
are accessed indirectly via the message port and not the traditional
MSR mechanism. Only UC, WT and WB cache types are supported.

We configure all the fixed range MTRRs with common values (VGA RAM
as UC, others as WB) and 3 variable range MTRRs for ROM/eSRAM/RAM as
WB, which significantly improves the boot time performance.

With this commit, it takes only 2 seconds for U-Boot to boot to shell
on Intel Galileo board. Previously it took about 6 seconds.

AFAIK, for all PLLs on all Tegra SoCs, the primary PLL output frequency
is (input * m) / (n * p). However, PLLP's primary output (pllP_out0) on
T210 is the VCO output, and divp is not applied. pllP_out2 does have divp
applied. All other pllP_outN are divided down from pllP_out0. We only
support pllP_out0 in U-Boot at the time of writing.

Fix clock_get_rate() to handle this special case.

This corrects the returned rate for PLLP to be 408MHz rather than 204MHz.
In turn, this causes high enough dividers to be calculated for the various
peripheral clocks that feed off of PLLP. Without this, some peripherals
failed to operate correctly. For instance, one of my SD cards worked
perfectly but an older (presumably slower) card could not be read.

Note that prior to commit 722e000ccd72 "Tegra: PLL: use per-SoC pllinfo
table instead of PLL_DIVM/N/P, etc.", the calculated PLL frequency was
816MHz since the wrong values were being extracted from the PLLP divider
register. This caused overly large peripheral dividers to be calculated,
which while wrong, didn't cause any correctness issues; things simply ran

mtd: nand: fsmc: Fixes and cleanup for fsmc_nand_switch_ecc()

This patch addresses some comments raised by Scott in the last versions.
Here the changes in detail:

- Removed __maybe_unused as its not needed
- Added check for strength == 4 and error out for the unsupported
  ECC strength values
- Don't set .caclulate, .correct, and .bytes for NAND_ECC_SOFT_BCH as this
  will be done in nand_scan_tail()
- Set .caclulate back to fsmc_read_hwecc() in the HW case
- Added comment that this function will only be called on SPEAr platforms,
  not supporting the BCH8 HW ECC (FSMC_VER8)

env: import: hashtable: Prevent buffer overrun when importing environment from file

Lets consider following scenario:
- One uses echo -n "key=value" to define environment variable in a file (single variable)
- The file content is "key=value" without any terminating byte (e.g. 0x0a or
0x0d).
- The file is loaded to u-boot non zero'ed RAM buffer (with load command).
- Then "env import -t -r $loadaddr $filesize" is executed.
- Due to lack of proper termination byte we have classical example of buffer
  overrun.

This patch prevents from this by allocating one extra byte than size and
explicitly null terminate it.

There should be no change for normal env import operation after applying
this patch.

9 years agofdt: add new fdt address parsing functions
Stephen Warren [Thu, 6 Aug 2015 21:31:02 +0000 (15:31 -0600)]
fdt: add new fdt address parsing functions

fdtdec_get_addr_size() hard-codes the number of cells used to represent
an address or size in DT. This is incorrect in many cases depending on
the DT binding for a particular node or property (e.g. it is incorrect
for the "reg" property). In most cases, DT parsing code must use the
properties #address-cells and #size-cells to parse addres properties.

This change splits up the implementation of fdtdec_get_addr_size() so
that the core logic can be used for both hard-coded and non-hard-coded
cases. Various wrapper functions are implemented that support cases
where hard-coded cell counts should or should not be used, and where
the client does and doesn't know the parent node ID that contains the
properties #address-cells and #size-cells.

dev_get_addr() is updated to use the new functions.

Core functionality in fdtdec_get_addr_size_fixed() is widely tested via
fdtdec_get_addr_size(). I tested fdtdec_get_addr_size_auto_noparent() and
dev_get_addr() by manually modifying the Tegra I2C driver to invoke them.

Much of the core implementation of fdtdec_get_addr_size_fixed(),
fdtdec_get_addr_size_auto_parent(), and
fdtdec_get_addr_size_auto_noparent() comes from Thierry Reding's
previous commit "fdt: Fix fdtdec_get_addr_size() for 64-bit".

imx: mx6ul: support mx6ul 9x9 evk board

This patch is to support mx6ul_9x9_evk board based on mx6ul_14x14_evk,
the difference between mx6ul 9x9 evk and mx6ul 14x14 evk are:
1. mx6ul 9x9 evk use pfuze3000, while mx6ul 14x14 evk use DCDC.
2. mx6ul 9x9 evk supports 256MB LPDDR2, while mx6ul 14x14 evk
   supports 512MB DDR3
3. mx6ul_9x9_evk use 9x9 package, while mx6ul_14x14_evk use 14x14 package.

This patch add the following:
1. Discard PHYS_SDRAM_SIZE from header file, use imx_ddr_size()
2. Introduce a macro is_mx6ul_9x9_evk using
   CONFIG_IS_ENABLED(TARGET_MX6UL_9X9_EVK) to avoid "#ifdef xxx" in non-SPL
   part. To SPL part, CONFIG_IS_ENABLED(TARGET_MX6UL_9X9_EVK) can not work,
   so still use "#ifdef CONFIG_TARGET_MX6UL_9X9_EVK" to differentiate with
   mx6ul_14x14_evk. And we have no way to dymaically checking this chip
   is 9x9 or 14x14.
3. mx6ul_9x9_evk use pfuze3000, so enabled POWER related configurations.
   POWER related configurations also effect for mx6ul_14x14_evk. But
   power_init_board implementation using 'if (is_mx6ul_9x9_evk())' to
   do initialization for mx6ul_9x9_evk, and do nothing for mx6ul_14x14_evk.
4. mx6ul_9x9_evk use lpddr2 with size 256MB, so add related SPL DRAM
   configurations.
5. Enable CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG and setting dtb file
   according to board_rev and board_name.
6. Add TARGET_MX6UL_9X9_EVK Kconfig entry

Commit 6a132416359e "ci_udc: Update the ci_udc driver to support bulk
transfers" caused the value of "len" to change without updating subsquent
users of that variable in ci_ep_submit_next_request(). This caused the
code that detects when to emit ZLPs (Zero Length Packets) never to
trigger, which in turn caused host timeouts when a ZLP was required,
which in turn broke tests/dfu/, even despite the assertion in that
commit's description that "These changes are tested for both the DFU and
lthor."

Fix this by modifying the added dtd iteration code not to modify "len",
but rather to keep state in a separate variable. Rename the variables
while we're at it so they describe their purpose better.
