by Angelo Dureghello 07 Nov '12

07 Nov '12

Hi, looking on freescale files, i found this possible issue line 65 out_be32(&fbcs->cscr0, CONFIG_SYS_CS0_CTRL); considering: CONFIG_SYS_CS0_MASK for m5235evb board is define CONFIG_SYS_CS0_CTRL 0x00001D00 and flexbus registers are as: typedef struct fbcs { u16 csar0; /* Chip-select Address */ u16 res1; u32 csmr0; /* Chip-select Mask */ u16 res2; u16 cscr0; /* Chip-select Control */ ..... this line should not work, applying 0000.

[U-Boot] [PATCH 0/7] lcd/video: Add parameter API and compressed bitmaps
by Simon Glass 07 Nov '12

07 Nov '12

This series contains patches to create an API to read lcd/video parameters such as the screen size. It also adds support for displaying compressed bitmaps. Ultimately it would be nice to unify lcd and video more, and this is a step towards that. Board files still need to decide which to use, but the same parameters are available in both.

[U-Boot] [PATCH v5 0/13] Port of MUSB driver from Linux (changes from Linux)
by Ilya Yanok 07 Nov '12

07 Nov '12

Current MUSB driver in U-Boot uses old UDC API while new gagdet client drivers need new gadget API. Also current MUSB driver has some significant limitations (like inability to handle tx for endpoints other than ep0). So I think port of new Linux driver is desirable. This is initial port, performed mostly by putting DM and OTG code under #ifndef __UBOOT__ clauses. My intention was to be as close as possible to the original to ease of possible resyncs. Some warnings are suppressed via CFLAGS. There are some style problems but I'm not touching them for now for the above mentioned reason. There is obviously some room for optimisation, some structure fields are unused as well as (probably) some code. This is not a replacement for existing MUSB driver (at least for now), cause there are still consumers of USB serial gadget which uses old API and there is no support for serial with new API for now. OTG and DMA are not supported. Ported drivers include: musb_dsps (should work both with TI AM33xx and TI81xx, tested only on AM33xx), am35x (tested on AM3517 EVM) and omap2plus (should work on OMAP2/3/4, tested on omap3_beagle, omap4_panda doesn't work and needs more work). Others should be easy to port too. Virtual root hub is not implemented but this shouldn't be a big problem as the old code has virtual root hub support enabled only for Blackfin platform. Pathes are rather big because of the original code size (and I didn't delete unused code, just disabled it). So it's probably better to look at changes as compared to Linux code. I prepared such version also, you can find it at [1]. Hopefully it will be also useful if resync with the kernel will be needed in future.

[U-Boot] Merging device trees at runtime for module-based systems
by Daniel Mack 07 Nov '12

07 Nov '12

Hi, a project I'm involved in uses a module/baseboard combo, and components on either board are described in DT. I'm currently using separate dts files which build upon each other with include statements, which works fine for development. In production though, we will certainly have running changes (and hence different versions) over the lifetime of the product for both the baseboard and the module, and the hardware has support for identifying the versions of both sides at runtime. So let's say we have n versions of the baseboard and m versions of the module, we would much like to only prepare n + m files, instead of n * m by pre-compiling every possible combination (some of which may actually never occur 'in the wild'). So my question is: is it possible to do that kind of assembly of a number of files at runtime in U-Boot? I guess all it takes is merging a number of trees together, right? I browsed through the APIs but couldn't yet find an clear approach to that kind of problem. If not, what would it take to add that functionality? I can probably help with the implementation if someone tells me what would be the right way. Any pointer greatly appreciated. Thanks, Daniel
