[U-Boot] [PATCH v2 00/27] spl: Use linker list and parameters for SPL image loading
by Simon Glass 07 Oct '16

07 Oct '16

At present the SPL code uses a global spl_image variable which is shared amongst lots of files, some in common/spl and some elsewhere. There is no need for this to be global, and in fact a parameter makes it easier to understand what information the functions act on. It also reduces the BSS use in the SPL (at the expense of stack) which is useful on boards which don't have BSS available early on. There are many global functions for loading images from each boot device type, like spl_mmc_load_image() and spl_spi_load_image(). Mostly these take the same parameters (none or a u32). There are various rules for compiling in calls to these functions and in some cases somewhat different rules for compiling in the functions themselves. For example, spl_spi_load_image() is called if either of CONFIG_SPL_SPI_SUPPORT or CONFIG_SPL_SPI__FLASHSUPPORT is enabled, but included in the image if CONFIG_SPL_SPI_LOAD is enabled. There is work in progress to look at that problem (Andrew F. Davis has sent some patches [1]), and this series does not address it. But even with that fixed its seems better to use a linker list and a consistent function signature for loading images. This series converts spl_image into a parameter and moves the SPL load functions into a linker list, where each method is declared in the file that provides it. The existing dispatching code is dropped. There is a priorty value attached to each loader which should allow the existing ordering to be maintained. Code size is about 20 bytes larger on average which I think is acceptable. The BSS size drops by about 64 bytes, but really this just transfers to the stack. There is an obvious follow-on from this, to move boot_name_table[] into the same linker list struct (i.e. add a name field to struct spl_image_loader). The complication here is that we don't want naming if CONFIG_SPL_LIBCOMMON_SUPPORT is not enabled, since it bloats the code. In addition I think that common/spl/spl.c can be tidied up a little. Finally, my reading of the load functions is that they could do with some rationalisation once we have a way to init any device without subsystem-specific function calls. For example, spl_sata.c and spl_usb.c contain very similar code but for the init methods.

[U-Boot] sf: proposed status register protect
by George McCollister 06 Oct '16

06 Oct '16

I'm looking into adding a sub-command to sf to protect status registers on Winbond SPI flash parts via the status register protect bits SRP0, SRP1. I propose the sub-command be named sr-protect. My use case is simple, I want to make the SPI flash read-only when the /WP pin is low. To do this I must do 'sf protect lock 0 $size' then set SRP0 to 1 and hold the /WP pin low. Although my use case doesn't require it, setting SRP1 to 1 allows either Power Supply Lock-Down or One Time Program (if supported by hardware) and I would probably add support for these as well. All of the current Winbond SPI NOR flash part datasheets that I've looked at show that the parts support the same locking implemented in stm_lock() even though SPI_FLASH_CFI_MFR_WINBOND is not in the list of vendors which use the function. I'll change this to make SPI_FLASH_CFI_MFR_WINBOND parts use stm_lock(), stm_unlock(), stm_is_locked(). spi_flash_protect() (which ultimately calls either stm_lock() or stm_unlock()) is not part of the driver model (dm_spi_flash_ops). Is there any issue with adding another function (let's call it spi_flash_sr_protect) that is not part of the driver model? Is anyone aware of any vendors other than Winbond that use this SRP mechanism or should only SPI_FLASH_CFI_MFR_WINBOND parts use it? For details see "7.1.7 Status Register Protect Bit (SRP1, SRP0)" on page 15 of http://www.winbond.com/resource-files/w25q64cv_revh_052214[2].pdf Cheers, George McCollister
