[U-Boot] [PATCH] ARM: compiler options cleanup - improve tool chain support
by Wolfgang Denk 07 Sep '09

07 Sep '09

For some time there have been repeated reports about build problems with some ARM (cross) tool chains. Especially issues about (in)compatibility with the tool chain provided runtime support library libgcc.a caused to add and support a private implementation of such runtime support code in U-Boot. A closer look at the code indicated that some of these issues are actually home-made. This patch attempts to clean up some of the most obvious problems and make building of U-Boot with different tool chains easier: - Even though all ARM systems basicy used the same compiler options to select a specific ABI from the tool chain, the code for this was distributed over all cpu/*/config.mk files. We move this one level up into lib_arm/config.mk instead. - So far, we only checked if "-mapcs-32" was supported by the tool chain; if yes, this was used, if not, "-mabi=apcs-gnu" was selected, no matter if the tool chain actually understood this option. There was no support for EABI conformant tool chains. This patch implements the following logic: 1) If the tool chain supports "-mabi=aapcs-linux -mno-thumb-interwork" we use these options (EABI conformant tool chain). 2) Otherwise, we check first if "-mapcs-32" is supported, and then check for "-mabi=apcs-gnu" If one test succeeds, we use the first found option. 3) In case 2), we also test if "-mno-thumb-interwork", and use this if the test succeeds. [For "-mabi=aapcs-linux" we set "-mno-thumb-interwork" mandatorily.] This way we use a similar logic for the compile options as the Linux kenrel does. - Some EABI conformant tool chains cause external references to utility functions like raise(); such functions are provided in the new file lib_arm/eabi_compat.c Note that lib_arm/config.mk gets parsed several times, so we must make sure to add eabi_compat.o only once to the linker list.

The ELDK fails to build the big-endian IXP boards, but this is a restriction of the ELDK, not a new issue introcued by this patch. Except of this, all build were succesful. Note 1: Please note that older tool chains (based on binutils versions older than 2.16) will have problems with the SORT_BY_ALIGNMENT() and SORT_BY_NAME() functions introduced to the linker scripts with commit f62fb99941c6. I'll soon submit a patch to fix this issue. Final tests are running right now. Note 2: Even though this is a bigger change, I consider it a bug fix and therefor tend to have it included into the upcoming release. Of course this requires sufficient test coverage and feedback. Please help!! Note 3: Most ARM systems also define this: PLATFORM_RELFLAGS +=$(call cc-option,-mshort-load-bytes,$(call cc-option,-malignment-traps,)) I guess this can be unified and moved to lib_arm/config.mk, too, but I would like to handle this in a separate, later patch. This makes testing (and bisecting) easier, and it is a non-critical problem. config.mk | 2 +- cpu/arm1136/config.mk | 2 -- cpu/arm1176/config.mk | 2 -- cpu/arm1176/s3c64xx/config.mk | 1 - cpu/arm720t/config.mk | 2 -- cpu/arm920t/config.mk | 2 -- cpu/arm925t/config.mk | 2 -- cpu/arm926ejs/config.mk | 2 -- cpu/arm926ejs/davinci/config.mk | 2 -- cpu/arm946es/config.mk | 2 -- cpu/arm_cortexa8/config.mk | 1 - cpu/arm_cortexa8/omap3/board.c | 7 ------- cpu/arm_intcm/config.mk | 2 -- cpu/ixp/config.mk | 1 - cpu/lh7a40x/config.mk | 2 -- cpu/pxa/config.mk | 2 -- cpu/s3c44b0/config.mk | 2 -- cpu/sa1100/config.mk | 2 -- lib_arm/Makefile | 15 ++++++++++++--- lib_arm/config.mk | 28 ++++++++++++++++++++++++++++ lib_arm/eabi_compat.c | 18 ++++++++++++++++++ 21 files changed, 59 insertions(+), 40 deletions(-) create mode 100644 lib_arm/eabi_compat.c diff --git a/config.mk b/config.mk index fd56621..0c6d1d1 100644 --- a/config.mk +++ b/config.mk @@ -86,7 +86,7 @@ ifdef ARCH sinclude $(TOPDIR)/lib_$(ARCH)/config.mk #

[U-Boot] ARM mach-types.h sync request
by Daniel Gorsulowski 07 Sep '09

07 Sep '09

Hi, according to http://lists.denx.de/pipermail/u-boot/2008-September/040553.html I request an update. It is needed for MACH_TYPE_ETHERCAN2 (based on MEESC board, patch will come soon.) The last kernel source was synced on 2009-06-20, and is also outdated. So please sync against http://www.arm.linux.org.uk/developer/machines/ Best regards Daniel Gorsulowski

[U-Boot] [PATCH-ARM 2/4] Clean-up of s3c24x0 header files
by kevin.morfitt＠fearnside-systems.co.uk 07 Sep '09

07 Sep '09

This patch re-formats the arm920t s3c24x0 header files in preparation for changes to add support for the Embest SBC2440-II Board. The changes are as follows: - re-indent the code using Lindent - make sure register layouts are defined using a C struct - replace the upper-case typedef'ed C struct names with lower case non-typedef'ed ones - make sure registers are accessed using the proper accessor functions - run checkpatch.pl and fix any error reports It assumes the following patch has been applied first: - [U-Boot][PATCH-ARM] CONFIG_SYS_HZ fix for ARM902T S3C24X0 Boards, 05/09/2009 - patch 1/4 of this series Tested on an Embest SBC2440-II Board with local u-boot patches as I don't have any s3c2400 or s3c2410 boards but need this patch applying before I can submit patches for the SBC2440-II Board. Also, temporarily modified sbc2410x, smdk2400, smdk2410 and trab configs to use the mtd nand driver (which isn't used by any board at the moment), ran MAKEALL for all ARM9 targets and no new warnings or errors were found.

[U-Boot] [PATCH-ARM 1/4] Clean-up of cpu_arm920t and cpu_arm920t_s3c24x0 code
by kevin.morfitt＠fearnside-systems.co.uk 07 Sep '09

07 Sep '09

This patch re-formats the code in cpu/arm920t and cpu/arm920t/23c24x0 in preparation for changes to add support for the Embest SBC2440-II Board. The changes are as follows: - re-indent the code using Lindent - make sure register layouts are defined using a C struct - replace the upper-case typedef'ed C struct names with lower case non-typedef'ed ones - make sure registers are accessed using the proper accessor functions - run checkpatch.pl and fix any error reports Note that usb_ohci.c still has two lines that exceed 80 characters. This is because the statements on those lines lose readability when wrapped - the Linux coding style guidelines allow for this. It assumes the following patch has been applied first: - [U-Boot][PATCH-ARM] CONFIG_SYS_HZ fix for ARM902T S3C24X0 Boards, 05/09/2009 Tested on an Embest SBC2440-II Board with local u-boot patches as I don't have any s3c2400 or s3c2410 boards but need this patch applying before I can submit patches for the SBC2440-II Board. Also, ran MAKEALL for all ARM9 targets and no new warnings or errors were found.

[U-Boot] reloacting uboot
by E Robertson 07 Sep '09

07 Sep '09

Hi All, I am using the at91sam9263 device from which the bootstrap code load u-boot to the desired ram address. However, I would like to re-relocate this at the different address based on memory availability. Can / or should this be done?

[U-Boot] [PATCH 1/8] USB Consolidate descriptor definitions
by Tom Rix 06 Sep '09

06 Sep '09

The header files usb.h and usbdescriptors.h have the same or similarly named structure definitions for usb_device_descriptor usb_string_descriptor usb_endpoint_descriptor usb_config_descriptor vs usb_configuration_descriptor usb_interface_descriptor There should only be one definition of these structures. Some of these structures are element-wise duplicates, one has unused elements that can be reduced to a duplicate, and some of the the structures have additional elements. These are the element-wise duplicates in usb.h usb_device_descriptor usb_string_descriptor For these, the usb.h definition will be removed. This definition in usb.h has extra unused elements usb_endpoint_descriptor unsigned char bRefresh unsigned char bSynchAddress; The definition of usb_endpoint_descriptor in usb.h will be removed. These definitions in usb.h have extra elements at the end of the usb 2.0 specified descriptor: usb_config_descriptor usb_interface_descriptor These structures will have their name shorted by removing the '_descriptor' suffix. So usb_config_descriptor -> usb_config usb_interface_descriptor -> usb_interface The common descriptor elements are now defined by the macros USB_CONFIG_DESCRIPTOR_DEFINITION USB_INTERFACE_DESCRIPTOR_DEFINITION This has been compile tested on MAKEALL arm, ppc and mips.

The value of I2C_TIMEOUT in fsl_i2c.c has several problems. First, it is defined as CONFIG_HZ/4, but it is used as a count of microseconds, so it makes no sense to derive it from a clock rate. Second, the current value (250) is too low for some boards, so it needs to be increased. Third, the timeout necessary for multiple-master arbitration is larger than the timeout for basic read/write operations, so we shouldn't have a single constant for both timeouts. Finally, it would be nice if we could override these values on a per-board basis.
