The bootrom code will reads init_boot_size to get the size of the second level loader(such as uboot) to load from storage to sdram when the BACK_TO_BROM function enabled. This patch set init_boot_size to init_size, so the bootrom will think that there is no second level bootloader, so it won't load it and jump to it. > > Signed-off-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com> > --- > > tools/rkcommon.c | 20 +++++++++++++++++--- > 1 file changed, 17 insertions(+), 3 deletions(-) > > diff --git a/tools/rkcommon.c b/tools/rkcommon.c > index cfd40ac..ed29ef9 100644 > --- a/tools/rkcommon.c > +++ b/tools/rkcommon.c > @@ -13,6 +13,8 @@ > #include "mkimage.h" > #include "rkcommon.h" > > +#define DIV_ROUND_UP(n, d) (((n) + (d) - 1) / (d)) > + > enum { > RK_SIGNATURE = 0x0ff0aa55, > }; > @@ -159,9 +161,21 @@ static void rkcommon_set_header0(void *buf, uint > file_size, > hdr->disable_rc4 = !rkcommon_need_rc4_spl(params); > hdr->init_offset = RK_INIT_OFFSET; > > - hdr->init_size = (file_size + RK_BLK_SIZE - 1) / RK_BLK_SIZE; > - hdr->init_size = (hdr->init_size + 3) & ~3; > - hdr->init_boot_size = hdr->init_size + RK_MAX_BOOT_SIZE / > RK_BLK_SIZE; > + hdr->init_size = DIV_ROUND_UP(file_size, RK_BLK_SIZE); > + /* > + * The init_size has to be a multiple of 4 blocks (i.e. of 2K) > + * or the BootROM will not boot the image. > + * > + * Note: To verify that this is not a legacy constraint, we > + * rechecked this against the RK3399 BootROM. > + */ > + hdr->init_size = ROUND(hdr->init_size, 4); > + /* > + * The images we create do not contain the stage following the SPL > as > + * part of the SPL image, so the init_boot_size (which might have > been > + * read by Rockchip's miniloder) should be the same as the > init_size. > + */ > + hdr->init_boot_size = hdr->init_size; > > rc4_encode(buf, RK_BLK_SIZE, rc4_key); > } > -- > 1.9.1 > > _______________________________________________ > U-Boot mailing list > U-Boot@lists.denx.de > https://lists.denx.de/listinfo/u-boot >

This change set adds documentation to the header0 initialisation and improves readability for the calculations of various offsets/lengths. As the U-Boot SPL stage doesn't use any payload beyond what is covered by init_size, we no longer add RK_MAX_BOOT_SIZE to init_boot_size.
