<f_> Anyone got a 2 GB lepotato?
<f_> (DRAM init things)
<f_> Currently libretech-cc_defconfig sets the rank mode so that only 1 GB is used. This works in 1 GB lepotato but on 2 GB lepotatoes only 1 GB can be used.
<f_> (in theory)
<f_> But later I'd like to add support and test other rank modes on gxl, so that 2 GB lepotato users are happy.
<f_> But then a problem will arise..how do we detect which rank mode is required?
<f_> BL2 just blindly tries to init using one then retries with another.

<f_> Not sure how, but SPL w/ SPL_PINTRL and new SPL_PINCTRL_MESON_GXL compiled?
<f_> No linking errors related to size?
<f_> $ ls -lh spl/u-boot-spl.bin
<f_> -rw-r--r-- 1 thelinuxmacbook thelinuxmacbook 41K Nov 24 14:08 spl/u-boot-spl.bin

<f_> narmstrong: Oh yes, and forgot one other thing I'd love to get up and running: DFU.
<f_> Double-checked and:
<f_> CONFIG_SPL_PINCTRL=y
<f_> CONFIG_SPL_PINCTRL_FULL=y
<f_> CONFIG_SPL_PINCTRL_GENERIC=y
<f_> <...>
<f_> CONFIG_SPL_PINCTRL_MESON_GX_PMX=y
<f_> CONFIG_SPL_PINCTRL_MESON_GXL=y

<f_> narmstrong: Does the meson driver replace some code from generic?
<f_> (oh and it still doesn't boot because of missing pinctrl nodes)

<f_> Oh wait CONFIG_SPL_PINCTRL_MESON isn't set..
<f_> >region `.sram' overflowed by 18368 bytes
<f_> It had to happen..

<narmstrong> f_: for dfu ?
<f_> That linking error?
<f_> SPL pinctrl size issues
<f_> Didn't work on SPL DFU yet

<f_> xdarklight: Am wondering if I was writing to the wrong register (eMMC pinctrl)?

ldevulder has joined #linux-amlogic
<f_> After writing to that register it fails to read anything. -EIO
<f_> With count == 0.
<f_> blk_dread specifically fails.

<lvrp16> time for TPL :D
<f_> nah, time for minifying SPL
jacobk has quit [Ping timeout: 245 seconds]
<f_> or finding a hacky way to get eMMC working.
<f_> xdarklight: The references to DAT_c88344cc you found ended up being unrelated to eMMC
<f_> (in the BL2 decompilation)
<f_> the register is being tampered with only when loading from SPI or when initialising the NAND, AFAICT
<f_> But then there's still that sdio_mmc_"init"() function...
<f_> But it doesn't seem to init anything
<f_> Aha.
<f_> pinmux_init
<f_> It plays with pinmux and checks if an SDIO debug board is connected, AFAICT
<f_> hm so eMMC *should* work?
