Hello,
I cleaned up the S5PV210/Tiny210 patches as discussed before.
Thank you for useful comments.
Alexey Galakhov (7):
Make S3C24xx config options available for all S3Cs
Split S3C generic and S3C24xx specific code
Add support for Samsung S5P architecture (S5PV210)
S5P boot header and image generator
S5P lowlevel clock init
S5P DRAM support
Add FriendlyArm Tiny210 board (S5PV210)

Ok. Sorry. BTW, there are functions like s3c_get_pclk(), and they are much worse than get_memory_size regarding their portability. Newer S3Cs have multiple clock domains, so there is more than one PCLK (i.e., MSYS-PCLK and HSYS-PCLK). These functions are declared publilc, not static, in a header file. They all are used in S3C24x0-specific code only. Should they be renamed like s3c24xx_get_pclk() ? Should some of them become static? _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox ^ permalink raw reply [flat|nested] 29+ messages in thread

But sometimes these functions should use a common name: when they are used by a shared driver. If you call a S3C2440 related function by a S3C2440 related driver or board file, we should use a SoC specific name. When we call a function from a driver used for S3C2440 *and* S3C6410 it should use a non SoC specific name. This is a "should" and I fear my S3C24xx code is not perfect in this way.

I think it's better to add 6410 and maybe Exynos first and then refactor. Newer Samsung chips are poorly documented, so it's hard to decide what's common and what's specific. (In fact, there are even errors in datasheets!) I.e., it turned out that s3c24x0_disable_wd() fits s5pv210 perfectly too without any change. (Just writing 0 into the first watchdog register disables the watchdog). This probably should be s3c_disable_watchdog(). I didn't touch it yet since I don't disable WD and I'm not sure about other CPUs.

I think in this case you have to make sure that s3c24xx-clocks.c is not compiled into the binary when s5p is enabled. Ideally we would have some debloated clk framework version from the kernel, but we are not there yet. We have the same situation on i.MX where imx_get_uartclk is implemented in each SoC. This is not very clean, but (still) does its job. I'm not asking you to make your port perfect in this regard, just please don't change things for worse which are already implemented the way they are supposed to be.

Most likely not. According to the datasheet, LPDDR/LPDDR2/DDR2 initialization sequence is completely different. It is in init_seq() function. Since I have no LPDDR(2) hardware to test, I coded the DDR2 version only. A runtime switch like that: switch(mode) { case LPDDR: lpddr_init_seq(); break; case LPDDR2: lpddr2_init_seq(); break; case DDR2: ddr2_init_seq(); break; } is too expensive for S5PV210's __bare_init which is very limited in space. Thus it is better to have only one function compiled in. Of course, it is possible to get rid of #ifdefs in s5p_init_dram_bank() but #ifdef is still needed for init_seq(). Ot is there any better solution?

Thus it is better to have only one function compiled in. I see. In this case you could provide a s5p_init_dram_bank_ddr2 which does the setup for ddr2 ram. The linker will then throw away any other eventually compiled in s5p_init_dram_bank_* function. Code common to all sdram setup functions could still be shared without overhead.
