kbuild: improve Kbuild speed
Kbuild brought about many advantages for us but a significant
performance regression was reported by Simon Glass.
After some discussions and analysis, it turned out
its main cause is in $(call cc-option,...).
Historically, U-Boot parses all config.mk
(arch/*/config.mk and board/*/config.mk)
every time descending into subdirectories.
That means cc-options are evaluated over and over again.
$(call cc-option,...) is useful but costly.
So we want to evaluate them only in ./Makefile
and spl/Makefile and export compiler flags.
This commit changes the build system as follows:
- Modify scripts/Makefile.build to not include config.mk
Instead, add $(PLATFORM_CPPFLAGS) to asflags-y, ccflags-y,
cppflags-y.
- Export many variables
Going forward, Kbuild will not parse config.mk files
when it descends into subdirectories.
If we want to set variables in config.mk and use them
in subdirectories, they must be exported.
This is the list of variables to get exported:
PLATFORM_CPPFLAGS
CPUDIR
BOARDDIR
OBJCOPYFLAGS
LDFLAGS
LDFLAGS_FINAL
(used in nand_spl/board/*/*/Makefile)
CONFIG_STANDALONE_LOAD_ADDR
(used in examples/standalone/Makefile)
SYM_PREFIX

RELFLAGS

- Delete CPPFLAGS
This variable has been replaced with PLATFORM_CPPFLAGS

We have to keep the same behavior with a different way.
By adding "CONFIG_" prefix, this macro appears

is reasonable enough.)
Tegra SoC family defined USE_PRIVATE_LIBGCC as "yes"

It means Tegra enables PRIVATE_LIBGCC only for SPL.
We can describe the same behavior by adding
Many (but not all) of Blackfin boards give -O2 option
to compile under lib/ directory.
That means lib/ should be speed-optimized,
whereas other parts should be size-optimized.

This is because when variable expansions are processed by make_string(),

no quoting is applied when doing so, so any empty variables simply don't
generate any parameter when the combined string is parsed again.
Fix this by explicitly replacing quoting any argument that was originally

integers. Commands which fail need to report the error and return 1
to indicate failure. Add this functionality in cmd_process_error().
For now this merely reports the error number. It would be possible
also to produce a helpful error message by storing the error strings
in U-Boot.

nand_spl: display warning message to inform the end of nand_spl
Now we have two different frameworks for doing the same thing.
I'd like to propose to drop nand_spl framework.
How about deleting it before v2014.07 release?
In the interim, this commit will display a warning message
when compiling nand_spl board.
They must be ported to SPL before the deadline,
otherwise they will be removed.

mtd: nand: omap: optimized chip->ecc.correct() for H/W ECC schemes
chip->ecc.correct() is used for detecting and correcting bit-flips during read
operations. In omap-nand driver it implemented as:
(a) omap_correct_data(): for h/w based ECC_HAM1 scheme
(b) omap_correct_data_bch() + CONFIG_NAND_OMAP_ECC_BCH8_CODE_HW_DETECTION_SW
for ECC_BCH8 scheme using GPMC and software lib/bch.c
(c) omap_correct_data_bch() + CONFIG_NAND_OMAP_ECC_BCH8_CODE_HW
for ECC_BCH8 scheme using GPMC and ELM
This patch updates (c)
- checks for calc_ecc[]==0x00 so that error_correction is not required for
known good pages.
- adds scalability for other ECC_BCHx scheme by merging following
omap_rotate_ecc_bch() + omap_fix_errors_bch() => omap_correct_data_bch()
- fixing logic for bit-flip correction based on error_loc[count]

mtd: nand: omap: optimize chip->ecc.calculate() for H/W ECC schemes
chip->ecc.calculate() is used for calculating and fetching of ECC syndrome by
processing the data passed during Read/Write accesses.
All H/W based ECC schemes use GPMC controller to calculate ECC syndrome.
But each BCHx_ECC scheme has its own implemetation of post-processing and
fetching ECC syndrome from GPMC controller.
This patch updates OMAP_ECC_BCH8_CODE_HW ECC scheme in following way:
- merges multiple chip->calculate API for different ECC schemes
omap_calculate_ecc() + omap_calculate_ecc_bch() + omap_calculate_ecc_bch_sw()
==> omap_calculate_ecc()
- removes omap_ecc_disable() and instead uses it as inline.

mtd: nand: omap: optimize chip->ecc.hwctl() for H/W ECC schemes
chip->ecc.hwctl() is used for preparing the H/W controller before read/write
NAND accesses (like assigning data-buf, enabling ECC scheme configs, etc.)
Though all ECC schemes in OMAP NAND driver use GPMC controller for generating
ECC syndrome (for both Read/Write accesses). But but in current code
HAM1_ECC and BCHx_ECC schemes implement individual function to achieve this.
This patch
(1) removes omap_hwecc_init() and omap_hwecc_init_bch()
as chip->ecc.hwctl will re-initializeGPMC before every read/write call.
omap_hwecc_init_bch() -> omap_enable_ecc_bch()
(2) merges the GPMC configuration code for all ECC schemes into
single omap_enable_hwecc(), thus adding scalability for future ECC schemes.
omap_enable_hwecc() + omap_enable_ecc_bch() -> omap_enable_hwecc()

arm: Switch to -mno-unaligned-access when supported by the compiler
When we tell the compiler to optimize for ARMv7 (and ARMv6 for that
matter) it assumes a default of SCTRL.A being cleared and unaligned
accesses being allowed and fast at the hardware level. We set this bit
and must pass along -mno-unaligned-access so that the compiler will
still breakdown accesses and not trigger a data abort.
To better help understand the requirements of the project with respect
to unaligned memory access, the
Documentation/unaligned-memory-access.txt file has been added as
doc/README.unaligned-memory-access.txt and is taken from the v3.14-rc1
tag of the kernel.
