Hi Haojian,

I have not had any reply to my email on my comment on v3: https://lists.linaro.org/pipermail/linaro-uefi/2017-February/003930.html where I point out that I have had no reply to my comment on v2: https://lists.linaro.org/pipermail/linaro-uefi/2017-February/003886.html

And none of the points I raise there appear to have been addressed.

Best Regards,

Leif

Hi Haojian,

I have not had any reply to my email on my comment on v3: https://lists.linaro.org/pipermail/linaro-uefi/2017-February/003930.html where I point out that I have had no reply to my comment on v2: https://lists.linaro.org/pipermail/linaro-uefi/2017-February/003886.html

And none of the points I raise there appear to have been addressed.

Actually I already applied those comments. But I don't have the DwUSB spec. My document only covers a few register definitions. I have to leave some hard code values since I don't know the definitions too.

OK, I noticed that the first few comments had not been addressed and assumed it applied throughout.

This is why it is useful to respond to review feedback rather than just submitting a new revision.

With that in mind...

For example, this one is not a hard-coded value, and yet my comment was not addressed.

OK, I'm not going to go through and point out which bits have been addressed or not.

Please go back to my reply from 7 February and respond to the comments I make in there. We can have a discussion about items you don't think it is correct or realistic to address in the way I suggest, or where you do not understand my comments.

This code is identical to v3.

In another thread in some other iteration, you stated "I need the terminated '\0' character. Since it'll be sent by USB driver. Without this, the last character will dispear."

Overall, I am very reluctant to accept this entire mechanism for retrieving strings, unless you can explain why this extremely roundabout way of putting a string into a buffer is necessary.

But this also requires going back and replying to my comments on 2/5.

StrLen ( IN CONST CHAR16 *String ) { UINTN Length;

ASSERT (String != NULL); ASSERT (((UINTN) String & BIT0) == 0);

for (Length = 0; *String != L'\0'; String++, Length++) { ... } return Length; }

We can find that it only counts the number of non-null character. When the USB driver gets the buffer and the size, it'll only send out all non-null characters. So the USB host will miss the null character as terminator.

In order to avoid this issue, I accumulate string length at here.

Support HiKey Fastboot driver for Fastboot App.

I asked a few questions on v3, which I received no replies to. Here I asked:

---

Question: I notice this version deletes the SPARSE_HEADER support, which was one of the main differences compared to VEXpress driver. Is this something you plan to introduce in future?

---

It'll be appended in future. There are two reasons that I remove it from this patch set. 1. There's some issue to download latest system.img into HiKey. 2. SPARSE_HEADER should be common case. It's better to parse it in AndroidFastboot App instead.
